Annan warns of severe crisis if Syria unresolved

GENEVA (Reuters) - International mediator Kofi Annan appealed to world powers to reach unity on a peace plan for Syria on Saturday, including principles for a Syrian-led political transition.

Annan, in opening remarks to a meeting of foreign ministers in Geneva, said the situation could ignite the region and develop into an international crisis if unresolved.

"An international crisis of grave severity now looms," he said. "We are here to agree on guidlelines and principles for a Syrian-led political transition that meets the legitimate aspirations of the Syrian people."
