Analysis of the Times and Locations of Critical Events in the Alleged Nerve Agent Attack at 7 AM on April 4, 2017 in Khan Sheikhoun, Syria

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.
