This analysis contains a detailed description of the times and locations of critical events in the alleged nerve agent attack of April 4, 2017 in Khan Shaykhun, Syria – assuming that the White House Intelligence Report (WHR) issued on April 11, 2017 correctly identified the alleged sarin release site.

Analysis using weather data from the time of the attack shows that a small hamlet about 300 m to the east southeast of the crater could be the only location affected by the alleged nerve agent release. The hamlet is separated from the alleged release site (a crater) by an open field. The winds at the time of the release would have initially taken the sarin across the open field. Beyond the hamlet there is a substantial amount of open space and the sarin cloud would have had to travel long additional distance for it to have dissipated before reaching any other population center.

Video taken on April 4 shows that the location where the victims were supposedly being treated from sarin exposure is incompatible with the only open space in the hamlet that could have been used for mass treatment of victims. This indicates that the video scenes where mass casualties (dead and dying) were laid on the ground randomly was not at the hamlet. If the location where the bodies were on the ground was instead a site where the injured and dead were taken for processing, then it is hard to understand why bodies were left randomly strewn on the ground and in mud as shown in the videos.

The conclusion of this summary of data is obvious – the nerve agent attack described in the WHR did not occur as claimed. There may well have been mass casualties from some kind of poisoning event, but that event was not the one described by the WHR.

The findings of this analysis can serve two important purposes:

  1. It shows exactly what needs to be determined in an international investigation of this alleged atrocity. In particular, if an international investigation can determine where casualties from the nerve agent attack lived, it will further confirm that the findings reported by the WHR are not compatible with the data it cites as evidence for its conclusions.
  2. It also establishes that the WHR did not utilize simple and widely agreed upon intelligence analysis procedures to determine its conclusions.

This raises troubling questions about how the US political and military leadership determined that the Syrian government was responsible for the alleged attack. It is particularly of concern that the WHR presented itself as a report with “high confidence” findings and that numerous high-level officials in the US government have confirmed their belief that the report was correct and to a standard of high confidence.

Methodology Used in This Analysis

The construction of the time of day at which particular video frames were generated is determined by simply using the planetary geometry of the sun angle during the day on April 4. The illustration below of the sun-angle geometry shows the Day/Night Sun Terminator at the location of Khan Sheikhoun on April 4. The angle of the sun relative to local horizontal is summarized in the table that follows the image of the planetary geometry along with the temperature during the day between 6:30 AM and 6 PM.

The next set of two side-by-side images shows the shadows at a location where a large number of poison victims are being treated in what appears to be the aftermath of a poisoning event. The shadows indicate that this event occurred at about 7:30 AM. This is consistent with the possibility of a nerve agent attack at 7 AM on the morning of April 4 and it is also consistent with the allegation in the WHR that an attack occurred at 6:55 AM on that day.

The timing sequence of the attack is important for determining the consistency of the timelines with the allegations of a sarin release at the crater identified in the WHR.

Assuming there was an enough sarin released from the crater identified by the WHR to cause mass casualties at significant downwind distances, the sarin would have drifted downwind at a speed of 1 to 2 m/s and for several minutes before encountering the only location where mass casualties could have occurred from this particular release. The location where these mass casualties would have had to occur will be identified and described in the next section. If there was a sarin release elsewhere, mass casualties would have not occurred at this location but would have occurred somewhere else in the city.

Assuming the victims of the attack were exposed to the plume, the symptoms of sarin poisoning would have express themselves almost immediately. As such, the scene at 7:30 AM on April 4 is absolutely consistent with the possibility of a mass poisoning downwind of the sarin-release crater.

The next figure shows the earliest photograph we have been able to find of an individual standing by the sarin-release crater where the alleged release occurred. The photo was posted on April 4 and the shadow indicates the time of day was around 10:50 AM. Thus the individual was standing by the crater roughly 4 hours after the dispersal event.

If the dispersal event was from this crater, the area where this unprotected individual is standing would be toxic and this individual would be subjected to the severe and possibly fatal effects of sarin poisoning. As a result, this throws substantial suspicion on the possibility that the crater identified by WHR would be the source of the sarin release.

At the time of the sarin release, the temperature of the air was about 60°F and the sun was at an angle of only 8° relative to local horizontal. This means that liquid sarin left on the ground from the dispersal event would remain mostly unevaporated. By 11 AM, the temperature of the air had risen to 75° and the angle of the sun relative to horizontal was at 66°. Thus, one would expect that the combination of the rise in air temperature and the sun on the crater would lead to significant evaporation of liquid sarin left behind from the initial dispersal event. The air temperature and sun angle are such that the area around the crater should have been quite dangerous for anybody without protection to operate.

This is therefore an important indication that the crater was probably not a dispersal site of the sarin.

The final set of three photographs shows arriving victims seeking treatment at a hospital at some location in Khan Sheikhoun. The arrivals at the hospital are at between 9 and 10:30 AM on the day of the attack. This is perhaps late since victims were seriously exposed by 7:30 AM, but victims could have been trailing in after the initial arrival of severely affected victims. This time is considerably earlier than the time at which WHR alleges that a hospital was attacked while treating victims of the poisoning attack.

In the next section we discuss the location where mass casualties should have occurred if the sarin release occurred at the location alleged by the WHR.

Identification of the Location of the Mass Casualties

The figure on the next page shows the direction of the toxic sarin plume based on the assumption that the alleged release point was the crater identified by WHR. The wind conditions at the time of the release, which would have been at about 7 AM on April 4, would have carried the plume across an empty field to an isolated Hamlet roughly 300 m downwind from the crater.

Although there were some walls and structures that would have somewhat attenuated and inhibited the movement of the aerosol cloud from the release point, the open field would be an ideal stable wind environment to transmit the remaining sarin cloud with minimal distortion and dispersal. As such, it is plausible that the sarin cloud could with the weather conditions at that time have led to mass casualties at the Hamlet.

The sarin dosage level that results in 50% of exposed victims dying is known as the LD50. The LD50 for sarin is about 100 mglmin/m3.

The dose quantity mglmin/m3 can be understood simply.

An exposure of about 100 mglmin/m3 simply means that a victim is within an environment for one full minute when there is 100 mg/m3 of sarin in the air. If the victim is instead in an environment for 10 minutes where there is a density of sarin of 10 mg/m3, they will also receive a lethal dose of 100 mglmin/m3.

Assuming 5 to 10 liters were aerosolized at the crater as alleged by the WHR, this would have resulted in an average sarin exposure at the Hamlet at 300 m range of about 10 to 20 mglmin/m3, assuming wind and temperature conditions that are near ideal for lethal exposures downwind. This estimate assumes that an individual would be outside and exposed to the sarin as the gas cloud passes by.

Postol 6Postol 7Postol 8Postol 9

Since a cloud of sarin would not be uniformly mixed, there will be regions in the cloud that have much higher and lower doses than the average. In addition, as the cloud passes, sarin entering into open windows of aboveground and basement rooms would tend to become trapped inside these rooms creating a significantly longer exposure to the nerve agent, certainly leading to lethal levels if residents did not evacuate the rooms immediately. Also, since the nerve agent cloud would be passing through an area that has buildings, it will tend to flow around, over buildings, and down into open basement windows, resulting in buildups of sarin in some locations and diminished levels of sarin at other locations.

As such, the Hamlet could well have been within lethal range of the sarin exposure. However, areas further downwind from the Hamlet would be sufficiently far away that the sarin will have dispersed sufficiently that it would not be capable of causing deaths.

Thus, the Hamlet area 300 m downwind of the crater is the only area where mass casualties could  occur if there had been a sarin release at the crater as alleged by the WHR!

The selected video frames collected on the next two pages show three important sets of data that indicate the following:

  1. Unprotected civilians with clothing that have logos of the Idlib Health Directorate are tampering with the contents of the crater crater that the WHR alleges was the source of the sarin release. All of the indicators point to a ruptured tube that could have contained no more than 8 to 10 liters of sarin. This is the only container shown in any videos from this scene.
  2. The next collection of video frames shows panoramic views of the target area taken from a drone equipped with a video camera. As can be seen in the video frames, a goat that was allegedly killed from the sarin dispersal is close to downwind of the alleged dispersal site.

However, the Hamlet that should have experienced major casualties if the alleged dispersal site had been correctly identified is only 300 m down range, and easily reachable by simply walking over to the site.

Yet none of the video journalists refer in any way to a mass casualty site nearby. They simply focus on a dead goat and present out of context images of a few dead birds. It is remarkable that no video journalists of the many who reported from this crater area referred in any way to the mass casualties that could only have occurred 300 m away if the attack had been executed from this crater.

  1. The last collection of 18 video frames is from the area where mass casualties were piled on the ground haphazardly dead or dying. Among these casualties were infants as well as men and women. This scene clearly could not have been at the location of the Hamlet as one can see that the walls surrounding the area are carved out of rock. Thus, this scene could not possibly have been at the Hamlet.

These video frames were generated by reviewing hundreds of videos posted on YouTube plus additional videos and video frames found on Twitter.

Among the hundreds of videos reviewed there seems to be no more than 50 to 60 seconds of actual original scenes like those laid out in the collection of 18 videos below. The vast majority of time in the videos contains the same repeated sequences of the same dead and injured infants and adults that could all be collected into less than a couple of minutes of independent scenes.

The overwhelming evidence is that these videos repeat nothing more than redundant scenes that suggest one terrible event might have occurred. Almost none of the scenes contain any different information from the others. This raises a serious question about how much real data has been supplied that would indicate an actual significant nerve agent attack.

What is absolutely clear from the videos is that the location of the sarin dispersal site alleged by WHR and the mass casualty site that would have had to be generated if the sarin dispersal actually occurred, are not in any way related to the scenes of victims shown in the other videos. The conclusion is obvious, the alleged attack described in WHR never occurred.

Final Comments

This abbreviated summary of the facts has been constructed entirely from basic physics, video evidence, and absolutely solid analytical methods. It demonstrates without doubt that the sarin dispersal site alleged as the source of the April 4, 2017 sarin attack in Khan Sheikhoun was not a nerve agent attack site.

It also shows beyond a shadow of a doubt that the only mass casualty site that could have resulted from this mass attack is not in any way related to the sites that are shown in video following a poisoning event of some kind at Khan Sheikhoun.

This means that the allegedly “high confidence” White House intelligence assessment ssued on April 11 that led to the conclusion that the Syrian government was responsible for the attack is not correct. For such a report to be so egregiously in error, it could not possibly have followed the most simple and proven intelligence methodologies to determine the veracity of its findings.

Since the United States justified attacking a Syrian airfield on April 7, four days before the flawed National Security Council intelligence report was released to the Congress and the public, the conclusion that follows is that the United States took military actions without the intelligence to support its decision.

Furthermore, it is clear that the WHR was not an intelligence report.

No competent intelligence professional would have made so many false claims that are totally inconsistent with the evidence. No competent intelligence professional would have accepted the findings in the WHR analysis after reviewing the data presented herein. No competent intelligence professionals would have evaluated the crater that was tampered with in terms described in the WHR.

Although it is impossible to know from a technical assessment to determine the reasons for such an egregiously amateurish report, it cannot be ruled out that the WHR was fabricated to conceal critical information from the Congress and the public.

The Nerve Agent Attack that Did Not Occur__Analysis of the Alleged Nerve Agent Attack at 7 AM on April 4_2017 in Khan Sheikhoun_Syrian_(April18,2017)_Optimized_

In a cover letter to his report, Dr. Postol also sent us the following Summary of Findings:

This analysis contains a detailed description of the times and locations of critical events in the alleged nerve agent attack of April 4, 2017 in Khan Shaykhun, Syria – assuming that the White House Intelligence Report (WHR) issued on April 11, 2017 correctly identified the alleged sarin release site.

Analysis using weather data from the time of the attack shows that a small hamlet about 300 m to the east southeast of the crater could be the only location affected by the alleged nerve agent release.  Video data of suffocating and dead victims lying on the ground shows a different location from the predicted sarin dispersal site if it had been correctly identified by the White House.

The conclusion is that the nerve agent attack described in the White House Intelligence Report did not occur as claimed.  There may well have been mass casualties from some kind of poisoning event, but that event was not the one described by the WHR.

The findings of this expanded analysis can serve two important purposes:

  1. It shows exactly what needs to be determined in an international investigation of this alleged atrocity.

In particular, if an international investigation can determine where casualties from the nerve agent attack lived, it will confirm that the findings reported by the White House Report are incompatible with its own cited data.

  1. It also establishes that the White House Report did not utilize simple and widely agreed upon intelligence analysis procedures to determine its conclusions.

This raises troubling questions about how the US political and military leadership determined that the Syrian government was responsible for the alleged attack.  It is particularly of concern that the White House Report presented itself as a report with “high confidence” findings and that numerous high-level officials in the US government have confirmed their belief that the report was correct and executed to a standard of high confidence.

    Someone should give that poor goat a shot of atropine and see in he comes around.

    But I’m president Donald a warmonger and neocon (apparently) too and I say this was the real deal and was no false flag operation. Our sources in the intelligence agencies are always right in matters like this. I’d trust them with my life and would bet my presidency on this fact…

    That whole area with the silos and where the goat died looks like it might be surrounded by a solid wall. Given that this area ( i.e. the corner with the dead goat ) was generally downwind of the crater , the presence of light – and potentially negligible – winds , and the fact that sarin vapor is heavier than air , I wonder about the possibility that the near-entirety of the released sarin vapor cloud might have been contained in there for some time , stalled against the southern wall of what was effectively a big , square bowl.

    The ~3 mph wind speeds posted could mean it was effectively dead calm in certain locales and times , so it might be hard to say exactly how the vapor cloud moved initially. If it did manage to collect in that square “bowl” ( most likely in the SE corner ) , it might have had the effect of re-concentrating the dispersed cloud , which could then have steadily leaked over the wall and/or “burped” over the wall by puffs of wind in anything ranging from numerous small burped clouds to one big one.

  • Marko

    I found a couple of pics of munition craters in asphalt roads that are reasonable facsimiles of the sarin pothole. The first one is from 1971 , and is titled : ” A 122 mm rocket impact crater at
    II Corps Headquarters, RVN, 1971 “. The second is simply described as being due to a roadside bomb.

    I lean towards the roadside bomb comparison , simply because Dr. Postol’s point about the externally-crushed section of pipe makes a lot of sense to me.

    With an explosion on top of the pipe , much of the soft asphalt road beneath may simply be collapsed and compressed , rather than flying up and out , explaining the minimal amount of debris.

      Chemical Ordinance, Artillery, 122mm rockets are fused to detonate above the target at altitude. They would not crash into the ground minimizing their effects. Ground detonated weapons would be the work of unsophisticated units. Professional Armies utilize air burst to disperse nerve agents.

      • Marko

        I agree. Dr. Postol suggests that the munition is likely a crude mock-up , made by cutting up 122 mm rockets from the junkyard.

        I doubt that any , but at most only a handful , of the CW attacks in Syria to date have used properly-designed ordinance. It’s all been jerry-rigged junk.

        They don’t care that much about efficiency of dispersion or lethality , they just want there to be an international stink about it , so the U.S. will hurry up and come over to carve up the country for them.

        • Dr Mindbender

          Yes, they sure botched it and anyone should be able to see that this was done by ISIS. They were in possession of bases, cites, and I am sure they captured stockpiled weapons. Setting them off, like such, is a total waste of the munition. If Assad was using Nerve Agent there would be thousands of Casualties.

          Also, I believe the workers shown “Above” ( at the site, and with patients) would have been killed working in such an area unprotected. Agent can linger around and be toxic “evaporating off of bodies”or other areas of collection. Full Suits and Full Respirators are mandated.

  • Dr Mindbender

    Nerve agent dispersed by areal bomb would aerosol over target. You would have a lot more casualties. The evidence shows an artillery piece, which if used properly, by a rocket launcher, would also detonate in the air over target for saturation. This looks like someone raided a weapons depot ( ISIS) and took a piece of ordinance and set it off in Hillbilly fashion. This weapon was not as effective used in this manner. There is no reason for ASSAD to do such a foolish thing, and all the evidence points towards ISIS, as we know they had access to these caches of weapons. Washington has a lot of nerve trying to blame ASSAD whereas if ASSAD used a MOAB, like little America, he would have had a Higher Death Count! A MOAB is nothing but a Cheap British “Tall Boy” with some Gasoline Jelly! The Cost of such an abomination should have sent US taxpayers into FULL RIOT MODE, if, they understood the Massive RIP OFF Ordinance!

  • More high quality analysis from Dr. Postol. The big weakness with false spy stories is that there are always some holes in the narrative because fiction doesn’t connect as many dots together as real events.

    I’m also noticing, here and on some other sites, that since Postol is introduced as “MIT Professor (emeritus)”, the same set of psyops who have been running around the internet attacking “fake news” web sites (mostly the one’s that challenge US govt. lying) as unworthy sources of anything, are out in mass today, challenging MIT professors as unworthy sources of anything, claiming they are either right wing or left wing depending on the audience the psyop is babbling at.

    • tom

      Unfortunately for the psy-ops, science is neither left wing nor right wing. It is interested only in truth, a commodity unfamiliar to all politicians.

  • MIT also covered up their successful confirmation of the LENR reports that Fleischmann & Pons showed to the world in 1989. Maybe because of the billion dollars they get for hot fusion research, maybe because of quiet compliance with oil industry, maybe because the military industrial complex wanted to cover it up for their own reasons.

    Eugene Mallove quit MIT over it and started a foundation to finance more experimentation. He was brutally murdered while cleaning a rental home in Connecticut. Search his name to find out more.

    Thank you, Professor Postol. Your analysis is convincing. And it matches with the background fact that no allegation that Syria uses chemical weapons has ever been proved, while Al Qaeda (Al Nusra) and ISIS are known possess chemical workshops and to make chemical attacks. Last week US bombers in eastern Syria struck a factory that then gave off chlorine gas, killing several local people, and just yesterday ISIS terrorists in Mosul in Iraq made three chemical weapons attacks:

  • tom

    Sadly, Dr Postol’s impressively professional work will go for naught. The cynical liars who published the White House Report will have known very well that their “report” didn’t begin to hold water. But hundreds of millions of Americans and others read the coverage of the WHR and will believe it (more or less).

    How many people will read and understand Dr Postol’s report?

  • seesee2468

    Please pardon my simple question, but could someone explain the apparent differences in wind directions indicated by the yellow arrows drawn on the photos (and the words of the explanatory text) and the wind directions given the first table in the Appendix? In the Appendix, the wind direction at 6 am on 4/4 is given as coming from the SE, which normally means the wind is blowing toward the NW, and the wind direction at 9 am is given as E, which means the wind would be blowing from the E toward the W. If the photos are oriented in a N-S direction, then the yellow wind-direction arrows drawn on the photos (and the words of the text) are pointing in the opposite directions to the normally defined directions. Is Dr. Postol using a special system here? I may be missing something obvious, but could someone explain?

    “When the government is speaking or acting, Jack observes his own Rule Number One: Always Assume It’s A Scam.” – Jack Perry.
    The longer I live and the more I read, I confirm Jack’s rule. It is with that purpose I started a website and a separate blog archive on Government/Religion/Politics/Culture to help myself and other mentors to gather useful data quickly for further study and dissemination. Here is a mother-lode of articles from various sources which clearly show the evidence that this ‘Assad did it’ is a sham and false flag – – and while you’re there, you can key word search for any other topics – the search on WW 1 and how the US got into it is truly a revelation of government lies and stupidity from 100 years ago – unlike anything you learned in Civics!
    Thanks for the post – Prof. Postol – it is now distributed and archived.
    Anyone can find my website linked from the archive or just googling my name.
    The search for truth and reality is a never ending project!

    During the Egyptian so called revolution the media aired a video of staged injury practice? The Egyptian media also showed an interview with young journalist who was recruited by the American embassy in Cairo to be trained on uprising. She said that she and about a dozen others were sent to REVOLUTION SCHOOL IN SERBIA to learn how to create violence by the police as the protesters are ready to record only the police violent response.
