Syrian rebels fighting to oust President Bashar al-Assad have called for safe havens and a no-fly zone near the borders with Jordan and Turkey.
The opposition calls for a foreign controlled no-fly zone and safe corridors will be raised today at a meeting of the Organisation of Islamic Cooperation.
Saudi Arabia has convened the gathering to discuss the idea and the worsening violence in the 17-month uprising.
It comes as battles rage for control of the northern city of Aleppo, Syria’s biggest city. Government tanks, artillery and snipers are said to have attacked rebels next to the devastated area of Salaheddine.
Meanwhile, the deputy police commander in the central province of Homs has become the latest official to join a steady trickle of desertions, according to the opposition Higher Revolution Council group.
There also appears to be more evidence of the devastation caused by fighting on the ground in other areas such as Deraa and Idlib.
One video to emerge allegedly shows the bodies of Syrian army offices thrown from a government building in the capital.
Anti-regime activists say at least 20 people were killed in the second day of a government offensive to retake a northern Damascus suburb.
