Lebanese guerrillas detonated a roadside bomb on Sunday while Israeli-allied militiamen were passing, killing one and wounding two others, security officials said.
The bomb was detonated by remote control about 2 p.m. as a South Lebanon Army militia vehicle traveled in the village of Tir Harfa, 11 miles south of this southern port city.
One militiaman was killed and two others were wounded, Lebanese security officials said on customary condition of anonymity.
The Iranian-backed Hezbollah, or Party of God, claimed responsibility.
Israeli troops and the militia allies retaliated by shelling suspected guerrilla hideouts near villages facing Israel’s self-proclaimed “security zone.” There were no reports of casualties in the shelling.
