Chemical attacks 'becoming routine' in Syria - US envoy

The US envoy to the international chemical weapons watchdog says the use of such toxic arms is "becoming routine in the Syrian civil war".
Rafael Foley was speaking on Monday at a closed meeting of the Organisation for the Prohibition of Chemical Weapons' Executive Council, which was called to discuss recent findings, including that a "non-state actor" likely used the chemical agent sulfur mustard in August during fighting in the Syrian town of Marea.
Foley says Syrian opposition forces were fighting the Islamic State group in the town close to the Turkish border.
The text of Foley's speech on Monday was posted on The Hague-based watchdog's website.

French Prime Minister Manuel Valls warned last week that associates of extremists responsible for the November 13 Paris attacks could use chemical and biological weapons.
