BEIRUT — The Lebanese army is on the move toward Nahr el-Bared. For the last three hours, the army has been pound­ing Fatah al-Islam posi­tions with artillery, tanks and mor­tars. Some believe this is a soft­en­ing up of posi­tion before a full-scale assault on the camp, which would break a 37-year-old prece­dent keep­ing Lebanese troops out of the Pales­tin­ian camps.
Or it might be another one of the exchanges of fire that have pep­pered the almost two week stand-off. Although this one looks pretty big.
