Russia circulated among UN Security Council members on Tuesday a draft resolution to extend a UN mission in Syria for three months so it can shift focus from monitoring a non-existent truce to securing a political solution to the conflict.

The deeply divided council must decide the future of the mission, known as UNSMIS, before July 20 when its initial 90-day mandate expires.

International envoy Kofi Annan is due to brief the council on Wednesday on his bid to broker peace in Syria.
