At least two people were killed and 20 others were wounded Friday when Lebanese troops opened fire on angry Palestinian refugees trying to march back home to their besieged camp in northern Lebanon, Palestinian officials said. Thousands of Palestinian refugees had fled the Nahr el-Bared camp where the army has been battling Islamic militants since May 20. Most have been sheltered since in the Beddawi camp, just 5 kilometers (3 miles) away, The Associated Press reported. But with the fighting dragging on between the military and the Fatah Islam militants holed up inside Nahr el-Bared, the displaced refugees are now demanding they be allowed to return to their homes.
