Fierce fighting between regime troops and armed rebels rocked parts of the Syrian capital Damascus overnight, a monitoring group said on Sunday.
"Violent clashes broke out between rebel fighters and regime troops at a checkpoint in Kafr Sousa district," the Syrian Observatory for Human Rights said in a statement.
There were no immediate details on casualties, the Britain-based watchdog added.
The Local Coordination Committees, an anti-regime network of activists on the ground in Syria, said that in the wake of the fighting, Kafr Sousa saw the "arrival of huge reinforcements" of regime troops.
Clashes also broke out in the south of the capital, the Observatory said, adding that gunfire had during the night echoed across the city center.
"Gunfire was heard in Abbasiyyin Square, and Baghdad and Thawra streets," said the monitor, referring to high-security areas of the city.
Meanwhile, regime forces shelled the outskirts of Douma, a bastion of anti-regime sentiment located near Damascus.
On Saturday, 23 people were killed in violence across Syria, the Observatory said.
More than 12,000 people, the majority of them civilians, have died in Syria since an anti-regime revolt broke out in March last year, according to the monitoring group.
