Lebanese Army on the Move

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.
