Hundreds of Palestinian civilians trickled out of a besieged refugee camp Wednesday after a truce in the fighting mostly held overnight. About 15,000 _ nearly half the camp's residents _ fled late at night when the lull took hold between Lebanese troops and militants barricaded in the crowded Nahr el-Bared refugee camp, relief officials said. About 1,000 fled Wednesday morning. Those fleeing reported bodies littering the camp's streets and scenes of blasted buildings and destruction. Officials said the bodies of at least 20 civilians have been retrieved from inside, the Associated Press reported.
