Three Lebanese soldiers were killed in fighting with Islamic extremists at a Palestinian refugee camp in northern Lebanon, a day after their families were evacuated, the military announced Sunday. The army said the three soldiers were killed Saturday "while carrying out their military duty" at the Nahr el-Bared camp. It did not elaborate or say how they were killed. The death toll of soldiers who have died since fighting between the army and al-Qaida-inspired Fatah Islam militants erupted three months ago has reached 145. On Friday, the families of the besieged militants who had been caught inside the camp - 25 women and 38 children - were evacuated, clearing the way for a final military assault against remaining fighters inside.
