Russia's deputy Foreign Minister Sergei Ryabkov says a UN Security Council resolution on Syria could mention Chapter VII of the UN Charter, which allows the use of force or sanctions against a sovereign state. Ryabkov said the measure could only be invoked if a chemical weapons accord, drafted by the US and Russia, was violated, an apparent change in Moscow's position.  Sverre Lodgaard, a chemical weapons disarmament specialist , explains that international law aims to eliminate chemical weapons.
