An advance United Nations team is expected in Damascus within 48 hours to discuss the deployment of cease-fire monitors in Syria.
As part of a peace plan proposed by UN-Arab League envoy Kofi Annan, some 250 UN observers would be sent to Syria for a monitoring mission.
Nonetheless, their deployment still requires approval under a UN Security Council resolution.
On April 2, Annan said Syrian President Bashar al-Assad had promised to withdraw troops and heavy weaponry from populated areas by April 10.
Confirmation of that withdrawal would lead to a cease-fire with opposition fighters.
Meanwhile, activists said heavy fighting engulfed opposition strongholds across the country on April 3 as Assad's regime continued a crackdown, which the UN says has killed more than 9,000 people in the past year.
