The Arab League has called for an emergency meeting to discuss whether to withdraw the group's monitors from Syria after reports that Syrian security forces are still killing anti-government protesters despite the observers' presence.
Deputy secretary-general, Ahmed bin Heli, said on Tuesday that the meeting will take place Saturday in Cairo.
There are about 100 Arab League monitors in Syria, dispatched to verify the regime's compliance with a plan to stop its crackdown on dissent.
On Monday, League chief Nabil Elaraby said Syrian troops are still killing anti-government protesters despite the presence of foreign monitors.
Activists say that in the week since the observers started their work in Syria on 27 December, hundreds have been slain.
