French intelligence services have scientific proof that the Syrian regime was responsible for a suspected chemical weapons attack that killed 88 people, France's foreign minister said Wednesday, according to AFP.
The minister, Jean-Marc Ayrault, said analysis of samples taken at the scene of the April 4 attack in rebel-held Khan Sheikhun, in which 31 children were among the dead, showed "there is no doubt that sarin gas was used" and that it was produced by Syrian laboratories.
