The U.N. peacekeeping force in southern Lebanon says the Israeli army has handed over data on cluster bombs fired during the 2006 war with the militant Hezbollah.

The move follows U.N. and Lebanese calls for information that could help eliminate the threat that has killed more than 20 civilians and wounded about 200 since the fighting.

A statement by the U.N. in Lebanon says the peacekeepers received "technical strike data and related maps" Tuesday and will pass them on to the Lebanese army.

The U.N. and human rights groups say Israel dropped about 4 million cluster bomblets during the monthlong war. Up to 1 million failed to explode and can detonate at the slightest disturbance.

Lebanon's south is also riddled with land mines.
