Cairo: Syrian opposition on Sunday rejected a United Nations-backed plan for a political transition in Syria.
The opposition groups have termed the plan as "ambiguous" and "a farce" while ruling out any possibility of sharing power with President Bashar al-Assad.
Earlier on Saturday, an international conference in Geneva accepted UN-Arab League joint envoy Kofi Annan's plan for the creation of a transitional government in Syria.
Addressing the meeting, Annan warned the participants - the United States, Russia, China, Britain, France and representatives from Arab countries - that if they failed to act, they could face an international crisis of "grave severity.''
