Russia on Saturday said the UN Security Council would act if Syria breached the international convention banning chemical weapons under a deal reached with the United States to eliminate its arms stockpile.
"In the case of those demands not being fulfilled, or in the case
of anyone using chemical weapons, the Security Council will take measures according to Chapter Seven of the United Nations charter," Lavrov said at a joint press conference with US Secretary of State John Kerry.
Lavrov referred to the section of the charter that provides for enforcement through sanctions, including the possible use of military force, saying that the Security Council expects Syria to comply fully with the demands of the Organisation for the Prohibition of Chemical Weapons.
Nevertheless, he cautioned that the Security Council would not accept reports of chemical weapons violations automatically but that they would be investigated.
"Of course it does not mean that each violation reported to the Security Council will be taken on trust. Each will be investigated. We will try to ensure authenticity," he said.
Lavrov praised the agreement between the US and Russia as a "consensus, a compromise and professional".
