Outside pressure builds on Syria as violence continues
Syria's leadership is under mounting pressure from other Arab states to halt its continuing violent repression of pro-democracy protests.
The head of the Arab League, Nabil al-Arabi, said the organisation was "studying mechanisms it could implement to protect civilians in Syria".
He spoke after the League voted to freeze Syria's membership, a move that sparked pro-government riots in Syria.
