Lebanese soldiers stake out the Nahr al-Baredcamp as part of a continuing siege [AFP]Jihad Omar, who is working with rescue teams in the centre of the camp, told Al Jazeera on Saturday that casualties were mounting and that wounded people were lying in the streets.
He said shelling continued in the centre of the camp where there were no Fatah al-Islam fighters, only civilians.The army has urged refugees still trapped inside the camp to "be patient and to expel those criminals from among you".Siniora said that the camp's population had fallen from more than 31,000 to fewer than 3,000, including the fighters, after civilians fled after the outbreak of fighting on May 20. He accused Fatah al-Islam of preventing the remaining civilians from leaving the camp in an apparent bid to use them as human shields.
