The ruler of the Gulf state of Qatar yesterday said Arab countries should send troops into Syria to stop government forces killing civilians there.
Sheikh Hamad bin Khalifa Al Thani told US television channel CBS "some troops should go to stop the killing".
It is the first time an Arab leader has publicly called for military intervention in Syria.
More than 5,000 civilians have been killed since anti-government protests erupted in Syria in March, the UN says.
The influential emir once had cordial relations with Damascus, but in recent months has become one of the most vocal Arab critics of the Assad regime as the Syrian strongman has repeatedly failed to curb the bloodshed.
