Assad regime 'used chemical weapons at least 14 times'

The Syrian regime used lethal chemical weapons on at least 14 occasions from 2012 prior to the attack on Damascus last week, the Joint Intelligence Committee has said.

"This judgement was made with the highest possible level of certainty following an exhaustive review by the Joint Intelligence Organisation of intelligence reports plus diplomatic and open sources," a JIC report said.

"We think that there have been other attacks although we do not have the same degree of confidence in the evidence."
