The 2007 siege of Nahr al-Bared was Lebanon's most intense internal conflict since 1990.
Beginning in May 2007, a brutal confrontation between the Lebanese Armed Forces and the militant group Fatah al-Islam transformed a Palestinian refugee camp into a war zone. The siege lasted months, involving heavy artillery, air strikes, and close-quarters combat, ultimately reshaping the security landscape of northern Lebanon.
The conflict ignited on May 20, 2007, following a police raid in Tripoli that targeted Fatah al-Islam militants. The group retaliated by attacking a military post at the Nahr al-Bared refugee camp, killing 27 soldiers. This sparked a protracted siege that drew in the Lebanese Armed Forces, who utilized tanks, artillery, and helicopters to suppress the militants. The camp, home to about 30,000 displaced Palestinians, became the epicenter of the most severe internal fighting in Lebanon since the 1975–1990 civil war.
The military campaign was marked by successive waves of attacks and failed cease-fire attempts. By June, the army had cleared the outskirts of the camp, but the militants remained entrenched in the center, utilizing booby-trapped buildings and subterranean shelters. The fighting was exceptionally difficult, characterized by hand-to-hand combat and the strategic use of air-to-ground missiles. As the siege dragged on, the humanitarian situation deteriorated, with civilians caught in the crossfire and the air becoming unbreathable due to the presence of unburied remains.
The conflict concluded in early September 2007 after a final, desperate breakout attempt by the militants. While the Lebanese Army successfully captured the camp by 11:00 AM on September 2, the leadership of Fatah al-Islam, including Shaker al-Abssi, largely managed to evade capture. The victory was met with celebrations in nearby villages, yet the event left a lasting mark on the nation, highlighting the deep-seated tensions surrounding Palestinian refugee camps, which had been categorized as foreign entities since 1962 and remained largely off-limits to the Lebanese government for decades.
