US official: 'IS making and using chemical weapons in Iraq and Syria'

7. We should know soon: UN to hold inquiry on Syria chemical attacks after Russia lifts objections

Security Council unanimously adopted resolution in August approving a joint investigation with the Organisation for the Prohibition of Chemical Weapons

Investigators will be charged with determining who is responsible for the attacks, which could lead to their being sanctioned by the Security Council. But any such sanctions would require a new resolution, which Russia could veto. According to diplomats, Moscow wanted guarantees on several points, notably that the sovereignty of its Syrian ally would be respected, and on the mission’s financing. The Syrian government is supposed to cooperate fully with the investigators.

Isis is suspected of having attacked Kurdish fighters with sarin gas last month in Iraq and in northern Syria.

The United States, Britain and France accuse the Syrian army of carrying out chemical attacks, including several with chlorine gas.

Russia, which has always protected its Syrian ally from its permanent, veto-wielding seat on the Security Council, contends there is no proof against Syria.

It sounds like the UN believes that chemical attacks occurred and that the UN "investigators will be charged with determining who is responsible for the attacks".
