Content:  The 2007 Lebanon conflict began when fighting broke out between Fatah al-Islam, an Islamic terrorist organization, and the Lebanese Armed Forces on May 20, 2007 in Nahr al-Bared, a Palestinian refugee camp near Tripoli. It has been the most severe internal fighting since Lebanon's 1975–90 civil war. The primary theater of conflict was the Siege of Nahr el-Bared.

The conflict finally ended on September 2, 2007 with the Lebanese Army taking control of the camp after more than three months of heavy fights and a death toll of 155 Commandos and Infantrymen. The LAF Engineering Corps achieved what was seen as a feat of ingenuity during the conflict where they converted a number of UH-1 helicopters into bombers, arming them with 250 kg and 400 kg conventional bombs from old Hunter and Mirage III fighter jets. Some helicopters were also fitted with French Matra rocket pods. This was, according to observers, a decisive step that considerably shortened the conflict.
