France confirms proof Assad regime behind deadly gas attack

France says it has proof that the Syrian government was behind the deadly chemical attack in Syria this month that left 89 people dead. French Foreign Minister Jean-Marc Ayrault confirmed that samples of the gas from the attack in the rebel-held town Khan Sheikhoun matched those of a previous incident. French laboratories kept samples from previous chemical attacks in Syria and compared the two. UK scientists previously confirmed that sarin, or a similar poison, was used in the attack after obtaining samples from the site.
