Insurgent commanders in the besieged town of Qusayr, near the Lebanese border, have appealed for help and warned of dire consequences if it does not arrive:
If all rebel fronts do not move to stop this crime being led by Hezbollah and Assad's traitorous army of dogs...we will soon be saying that there was once a city called Qusayr.
Malek Ammar, an opposition activist in Qusayr, said, "The town is surrounded and there's no way to bring in medical aid."
Ammar said about 100 of 700 wounded needed oxygen: "What we need [insurgent units] to do is come to the outskirts of the city and attack the checkpoints so we can get routes in and out of the city."
Qusayr has been under sustained shelling and attacks for almost two weeks. On Wednesday, the Syrian military captured the nearby airbase of Dabba, cutting off the town on all sides and bolstering their positions.
Elsewhere, insurgents blockaded in the eastern Ghouta, east of Damascus, appealed for help on Facebook, claiming Assad's forces were "preparing to commit more massacres".The fighters said they held the opposition Syrian National Coalition, whose members have spent a week arguing in Istanbul over the orgnaisation of the leadership, responsible for their plight.
George Sabra, the acting head of the opposition Syrian National Coalition, has confirmed that the group will not attend any international "peace" conference.
However, whereas the Coalition's formal declaration on Wednesday emphasised its demand that President Assad step down as part of any transitional government, Sabra's statement said the condition was the international community's intervention to end the Syrian military's siege of Qusayr, near the Lebanese border.
Then Sabra declared, "The National Coalition will not take part in any international conference or any such efforts so long as the militias of Iran and Hezbollah continue their invasion of Syria."
