JERUSALEM -- Israel is calling for a United Nations investigation into an explosion at a home of a Hezbollah member in the southern Lebanese village of Tayr Filsi Monday. Israeli leaders suspect the explosion occurred because Hezbollah was storing arms and munitions at the home. 

Israel accuses the terrorist group of keeping weapons and ammunition illegally throughout southern Lebanon, in violation of the cease fire agreement that ended the war between Israel and Hezbollah in 2006.

According to initial Lebanese media reports, a senior Hezbollah official and several others were killed in the blast. But Hezbollah and the Lebanese Army claim that no one was killed and only one person was wounded.

Israel's government wants UNIFIL (United Nations peace keeping forces) to explain why Hezbollah is apparently able to store large caches of arms in southern Lebanon despite the presence of more than 12 thousand U.N. troops designated to monitor the cease fire.

Israeli President Shimon Peres said Tuesday that Hamas is turning Lebanon into a "powder keg."

Defense officials in Israel say another southern Lebanon home which exploded in July contained dozens of Katyusha rockets.
