Syria has rejected an Arab League call for President Bashar al-Assad to hand over power to his deputy.
The league, meeting in Cairo, also called on Syria to form a national unity government with the opposition within two months.
A government official called the plan "flagrant interference" in Syria's internal affairs, state TV said.
The UN says more than 5,000 people have died as a result of the crackdown on protests since they began last March.
The league called on both sides to end the bloodshed.
The government in Damascus says it is fighting "terrorists and armed gangs" and claims that some 2,000 members of the security forces have been killed.
