Several people have been killed and many more injured after armed groups clashed with Syrian security forces in the southern city of Daraa.
Syrian authorities say at least seven people, including four soldiers, were killed during the overnight clashes in the city. Some reports, however, put the death toll at 25.
Witnesses say thousands of Syrian troops backed by tanks have entered Daraa.
Syrian authorities blame armed groups and foreign elements for the violence.
Damascus has repeatedly denied allegations that security forces are responsible for the death of protesters, saying they have been given clear instructions not to hurt civilians.
According to human rights activists, hundreds of people have been killed since the beginning of protests in Syria in mid-March.
Two Syrian lawmakers have resigned to protest against security forces' failure to protect the people. The mufti of Daraa is also reported to have resigned.
