UK Foreign Secretary William Hague said: "From the wealth of technical detail in the report - including on the scale of the attack, the consistency of sample test results from separate laboratories, witness statements, and information on the munitions used and their trajectories - it is abundantly clear that the Syrian regime is the only party that could have been responsible."

US ambassador to the UN Samantha Power used similar language when saying: "The technical details of the UN report make clear that only the regime could have carried out this large-scale chemical weapons attack."

She also pointed out that the 122mm rockets cited in the report were of the type previously associated with government forces and that the quality of the sarin was higher than that used by Saddam Hussein in Iraq.

French Foreign Minister Laurent Fabius said: "When you look at the findings carefully, the quantities of toxic gas used, the complexity of the mixes, the nature, and the trajectory of the carriers, it leaves absolutely no doubt as to the origin of the attack."
