The Israeli–Lebanese conflict, or the South Lebanon conflict, is a long-running conflict involving Israel, Lebanon-based paramilitary groups, and sometimes Syria. The conflict peaked during the Lebanese Civil War. In response to Palestinian attacks from Lebanon, Israel invaded the country in 1978 and again in 1982. After this it occupied southern Lebanon until 2000, while fighting a guerrilla conflict against Shia paramilitaries. After Israel's withdrawal, Hezbollah attacks sparked the 2006 Lebanon War. A new period of conflict began in 2023, leading to the 2024 Israeli invasion of Lebanon.
