Violence has fallen in Syria as a fragile ceasefire takes hold, although both sides are reporting violations.
Syrian state TV said a roadside bomb in the city of Aleppo had killed one person and wounded 24.
The opposition said three people had been killed in Idlib and Hama and there was "no evidence" of a significant withdrawal by Syrian troops.
Special envoy Kofi Annan, who brokered the ceasefire, said he was "encouraged" but Syria had not fully complied.
"All parties have obligations to implement fully the six-point [peace] plan. This includes both the military provisions of the plan and the commitment to move to a political process," Annan told the UN Security Council.

Six Point Peace Plan:
1. Syrian-led political process to address the aspirations and concerns of the Syrian people
2. UN-supervised cessation of armed violence in all its forms by all parties to protect civilians
3. All parties to ensure provision of humanitarian assistance to all areas affected by the fighting, and implement a daily two-hour humanitarian pause
4. Authorities to intensify the pace and scale of release of arbitrarily detained persons
5. Authorities to ensure freedom of movement throughout the country for journalists
6. Authorities to respect freedom of association and the right to demonstrate peacefully
