Hezbollah guerrillas have staged their first attack in months on Israeli troops in the disputed border area known as Shebaa Farms. Sunday's attack triggered a fierce cross-border artillery duel and retaliatory Israeli air strikes.

The United Nations said one of its peacekeepers was killed by Israeli fire, while Israeli says one of its soldiers was killed by a roadside bomb. The Lebanese Shi'ite militant group also claims to have wounded several others in the bombing.

Shebaa Farms was captured by Israel in the 1967 war. Lebanon and Syria say the area is Lebanese territory; the United Nations says it is Israeli-occupied Syrian land.

Hezbollah has vowed to continue attacks until Israel leaves the Shebaa Farms area.
