Russia and China have introduced a draft U.N. resolution aimed at preventing "terrorists" from preparing or using chemical weapons in Syria.

Russia's U.N. Ambassador Vitaly Churkin told reporters Wednesday that there have recently been numerous reports "of terrorist groups in Syria and neighboring Iraq using chemical weapons."

He said the proposed resolution will fill the "missing link" in current resolutions dealing with Syrian chemical weapons.

Churkin said it will require countries — especially Syria's neighbors — to immediately report any actions by extremist groups to acquire, develop or transfer chemical weapons to the Security Council and the international body charged with establishing who is responsible for chemical attacks in Syria.

He called the proposed resolution a limited but necessary step that may serve as a deterrent.
