Lebanon was dragged into the conflict on Monday, when the Iran-backed militant group Hezbollah attacked Israel to avenge the killing of Iranian supreme leader Ayatollah Ali Khamenei in the US-Israeli strikes that launched the war. Israel responded with air strikes and sent ground troops into some Lebanese border villages, and told residents of a large area of south Lebanon to leave in anticipation of military operations there.
