Heavy fighting grips Syrian cities

Gunbattles rage in the streets of Syria.

Violence continued throughout the weekend, including fighting in Deraa, where rebels in this footage purportedly fire on army positions.

Other footage is said to show heavy fire in Aleppo.

This video, and many others like it posted online can't be independently verified by Reuters.

Meeting with UN special envoy Lakhdar Brahimi in New York, Syrian Foreign Minister Walid al-Moallem said other countries must be stopped from funding and arming rebels.

Despite government promises of cooperation, the UN mission has made little progress to end the conflict after several months on the ground.
