JERUSALEM - The Israeli army said Monday it uncovered four bombs on the Israeli side of the border with Lebanon and accused Hezbollah guerrillas of planting the explosives in recent days.

If confirmed, it would mark a violation of a U.N.-brokered cease-fire by Hezbollah and indicate a failure by international peacekeepers to prevent new attacks on Israel.

Lt. Col. Guy Hazoot, the operations officer of Israel's northern division, said an Israeli patrol discovered and detonated all of the explosives, which were hidden in containers that looked like boulders. He said the explosives were designed to target Israeli military patrols on the border and had the potential to kill.

Hazoot said the bombs were planted as recently as Sunday night, under the cover of stormy weather, but gave no evidence to back the allegation. The military conducts routine patrols in the area.

Israel and Hezbollah fought a 34-day war last summer. The border area has largely remained quiet since the Aug. 14 cease-fire took hold.

Under the cease-fire, thousands of international peacekeepers, along with Lebanese government troops, police the border to ensure quiet. The deal bars Hezbollah guerrillas from carrying arms in the border area.

Hazoot said UNIFIL peacekeepers have thwarted similar Hezbollah attempts to lay roadside bombs in the past, but had failed to do so this time.

"We view the Lebanese army as responsible for this event," he said. "We will take all the necessary steps to make sure that these such events do not recur."

There was no immediate reaction from Lebanese, Hezbollah or U.N. officials. -AP
