A day after another apparent Hizbullah arms cache explosion in southern Lebanon, President Shimon Peres said that the guerrilla group had turned Lebanon into a powder keg that in the end would hurt Lebanon itself.
The president added that there was no reason for there not to be peace between Israel and Lebanon.
"We have evacuated all of the territory and are now extending a sincere hand to the Lebanese people. Lebanon could have long since become the Switzerland of the Middle East," he said. "It is Hizbullah and Hamas that are preventing this economic flowering and peace and security in the region."
Senior military sources said that the explosion near Tyre late Monday night was proof of continued Hizbullah violations of UN Security Council Resolution 1701.
Lebanese security officials said the explosion occurred in a building in the village of Tayr Filsay about six kilometers north of Israel that was likely used as a Hizbullah weapons depot.
At least one person was killed, with Reuters reporting as many as five deaths. The state-run National News Agency reported that the explosion destroyed the three-story building.
The IDF filed a complaint with UNIFIL and demanded that the peacekeeping force launch an investigation into the incident.
According to Lebanese news reports, the building belonged to Abdul Nasser Issa, a senior Hizbullah operative who may have been killed in the explosion.
Hizbullah said no one was killed but one person was wounded. In a statement on the Web site of its Al-Manar TV station the terror group said that an investigation was underway to determine the cause of the blast, which it said took place in the garage of a home belonging to one of its members.
Other reports claimed that the explosion was caused by IDF ordnance left behind following the Second Lebanon War in 2006. Defense officials rejected the claim.
"This is proof of the existence of illegal weaponry in southern Lebanon," IDF sources said, referring to a similar explosion in July in the village of Hirbet Selm when a home hiding a major Hizbullah arms cache exploded. According to the IDF, the cache in Hirbet Selm was hidden in a home in the village and contained dozens of 122mm Katyusha rockets.
"Hizbullah uses civilians as shields to protect its weaponry," an Israeli defense official said, adding that according to intelligence, the Lebanese guerrilla group was storing arms caches in dozens of additional villages in southern Lebanon.
UNIFIL spokeswoman Yasmina Bouziane said the force was in touch with the Lebanese Army "to try to confirm the circumstances of the explosion."
The Lebanese army issued a statement saying an Israeli reconnaissance plane flew over south Lebanon earlier Monday, but made no mention of the explosion, according to the state news agency report.
