Two Lebanese Red Cross workers have been killed outside a Palestinian refugee camp where troops are battling Islamist fighters. The two were evacuating civilians when they were hit by either machine gun or shell fire from the Nahr al-Bared camp. Lebanese troops have been trying to crush the radical Islamist group since fighting first broke out in the camp on May 20. Some 3,000 civilians are still thought to be inside the camp, which contained an estimated 30,000 people before the violence began. (BBC)
