Two Lebanese soldiers have been killed in continued fighting between the army and al-Qaida-inspired militants entrenched in a Palestinian refugee camp in northern Lebanon, a senior military official reported Saturday. The army has been advancing slowly into Nahr el-Bared camp, targeting the fortifications and tunnels used by Fatah Islam fighters, the official said, speaking on condition of anonymity because he was not authorized to speak to the media. One soldier died Saturday and another a day earlier, the official reported, raising to 133 the number of troops killed since fighting erupted May 20. "Every day there is progress," said the official, adding that troops were being cautious because of the presence of civilians in the area controlled by Fatah Islam. Most civilians left the camp shortly after the fighting began, but some family members of the gunmen have remained.
