Fighting in Syria has marred the first day of a ceasefire over the Muslim holiday of Eid al-Adha.

The worst incident of violence was a bombing in the capital that killed five people and injured at least 30.

Fighting also continued in the town of Haram, and witnesses just across the border in Turkey reported hearing machine-gun fire and the sound of shelling.

Syrian state TV says several people were killed and dozens wounded by a car bomb in the capital, Damascus.

The bomb exploded near a temporary playground set up for the holiday period and children are among the casualties.
