Arab League leaders have called for the immediate implementation of a joint plan with the UN to end a year of violence in Syria.
Syria's President Bashar al-Assad has accepted the plan, state media report, but says "terrorism" must stop as well.
President Assad's remarks were contained in a message to the world's emerging powers - Brazil, Russia, India, China and South Africa - who met in Delhi yesterday.
He said he would work to enforce the peace plan but "terrorism" must stop as well, state news agency Sana reported.
Earlier, Iraq's PM Nouri al-Maliki warned that arming either side in Syria would lead to a "proxy war".
He was speaking at the opening of an Arab League summit in Baghdad - the first such meeting there for decades.
A number of explosions were heard in central Baghdad as the summit was getting under way.
