Massachusetts Institute of Technology Professor Theodore Postol, who wrote a preliminary review of the U.S. government claims earlier this week and shared his findings with RT, examined photographs of the attack site and concluded that the report endorsed by the White House "could not be true".
Britain's UN Ambassador Sir Matthew Rycroft informed the United Nation Security Council (UNSC) that the samples taken from the rebel-held town of Khan Sheikhoun and analysed by British scientists had tested positive for sarin or a sarin-like substance, reports the Independent.
Postol's six-page addendum, made public on Thursday evening, "unambiguously shows that the assumption in the [White House report] that there was no tampering with the alleged site of the sarin release is not correct". "This egregious error raises questions about every other claim in the WHR".
That assumption was "totally unjustified", wrote Postol, "and no competent intelligence analyst would have agreed that this assumption was valid." .
Postol's key argument is a series of photographs of the crater where the container holding sarin was supposedly air-dropped.

As the train approached Kikar Tzahal, he reportedly stood up from his seat, pulled out a knife and stabbed a fellow passenger. The British Embassy in Israel said it was "in touch with local authorities" but could not give any further comment.
A joint investigation by the OPCW and the United Nations a year ago had also established that Syrian regime leader Bashar al Assad's forces carried out at least two chemical attacks and that DAESH had used mustard gas as a weapon in the conflict that has ravaged Syria since 2011. Speaking to the Catholic News Service in an interview, Syrian Catholic Patriarch Ignace Joseph Younan labeled the strike as an aggression and suggested that the us should have waited for the United Nations to finish an investigation into the origin of the chemical attack. Washington said that account was not credible, and rebels have denied it.
The United States, Turkey and other Western states have blamed the regime of Syrian President Bashar al-Assad for the deaths. The World Health Organization soon after the attack said that the victims' symptoms strongly suggested the use of Sarin or a similiar substance.
The mission will determine whether chemical weapons were used, but is not mandated to assign blame.
This is while several countries, led by Russian Federation and Iran, have strongly challenged Western-led efforts to probe the alleged chemical attack in Syria as inadequate, biased, and politically-motivated.
