Syria crisis: France calls for UN to enforce Annan plan

French Foreign Minister Laurent Fabius has said he will call on the UN Security Council to make mediator Kofi Annan's peace plan fro Syria mandatory.

France will propose that Mr Annan's six-point plan be enforced under the UN's Chapter Seven provision, he said.

Mr Fabius said the conflict in Syria had descended into a "civil war".

Meanwhile, US Secretary of State Hillary Clinton has warned Russia that its interests in the region will be harmed if it does not act more constructively.

Earlier on Wednesday, Syrian forces seized control of the western mountain town of Haffa after fierce fighting with rebels.
