In Lebanon, the primary responsibilities of the Lebanese Armed Forces (LAF) are defense against external attack, border security, protecting the country’s territorial waters, and assisting with internal security and development projects; on
Lebanon’s eastern and northern borders with
Syria, the LAF has conducted operations to prevent or eliminate infiltrations of militants linked to the Islamic State of
Iraq and ash-Sham (ISIS) and al-Qa’ida terrorist groups since the start of the Syrian civil war in 2011; in the south, its focus is on maintaining stability along its volatile land border with
Israel where the LAF and the
Israel Defense Forces (IDF) are separated by the "Blue Line," a demarcation line established by the UN in 2000 following the withdrawal of the IDF, which had occupied southern
Lebanon since invading in 1982; since the line’s establishment, the LAF and IDF have had periodic clashes, and IDF aircraft have routinely entered Lebanese air space
the Iranian-backed terrorist group Hizballah is based in south
Lebanon where it has significant influence and acts as a militia alongside the LAF; it has launched periodic cross-border attacks on
Israel and threatened additional attacks, while the IDF has conducted air strikes on Hizballah positions and in 2006 launched a ground invasion into southern
Lebanon to suppress the group; following the terrorist group HAMAS's attack on
Israel from Gaza in October 2023 and subsequent Israeli invasion of Gaza, Hizballah has sought to demonstrate solidarity with HAMAS by launching barrages of missiles, rockets, and armed drones into northern
Israel; these attacks continued into 2024 and have been countered by numerous strikes from
Israel on Hizballah targets in
Lebanon the LAF’s domestic security responsibilities include countering narcotics trafficking and smuggling, managing protests, conducting search and rescue, and intervening to prevent violence between rival political factions; in recent years, the military has faced a financial crisis as government debt and national economic difficulties have undercut its ability to train and fully pay and supply personnel, which has sparked domestic and international fears that the armed forces may disintegrate; the UN, as well as individual countries such as
France and the US have provided financial assistance
the UN Interim Force In
Lebanon (UNIFIL) has operated in the country since 1978, originally under UNSCRs 425 and 426 to confirm Israeli withdrawal from
Lebanon, restore international peace and security, and assist the Lebanese Government in restoring its effective authority in the area; following the July-August 2006 war, the UN Security Council adopted resolution 1701 enhancing UNIFIL and deciding that in addition to the original mandate, it would, among other things, monitor the cessation of hostilities, support the LAF as they deployed throughout the south of
Lebanon, and provide assistance for humanitarian access for civilians and the return of displaced persons; UNIFIL has approximately 9,500 military personnel deployed in the country and includes a maritime task force (2024)
