Damascus: President Bashar al-Assad has agreed to a peace plan by envoy Kofi Annan to end the crisis in Syria and vowed that he would spare no effort to make it succeed, the state agency said on Thursday.

"President Assad has informed Annan that Syria approves the plan (the envoy) submitted but had made remarks about it," SANA said without elaborating.

The agency added that Assad had underlined that he would "spare no effort" to make the six-point plan work.

It said Assad's remarks were made in a message to the world's emerging powers meeting Thursday in New Delhi.
