Violence has flared in and around Tripoli since last summer, explains Al-Ahram weekly, an English newspaper published in Egypt.
[L]ast summer, soldiers fought a 16-week battle with Al-Qaeda-inspired militant group Fatah Al-Islam, losing 170 soldiers. The gunmen, of Lebanese, Palestinian and other Arab nationalities, were holed up in the Nahr Al-Bared Palestinian refugee camp, just north of Tripoli. Fatah Al-Islam leader Shaker Al-Abssi and other fighters slipped away during the battle and remain at large. The fighting levelled the camp, home to roughly 30,000 Palestinians.
