An Israeli soldier was killed in clashes with Hezbollah militia forces in the village of Dabel in southern Lebanon early on Tuesday, an army spokesman said.
"At least 15 Hezbollah men were killed in the fighting," a military source said.
The spokesman said the dead soldier was among a force walking near an engineering corps vehicle, which was hit by an anti-tank missile.
Five soldiers were lightly injured in the incident, which followed intense clashes in Dabel, near the Hezbollah stronghold of Bint Jbeil.
The death brought to 62 the number of Israeli troops killed since the capture of two soldiers in a deadly Hezbollah raid on July 12 that triggered the offensive on Lebanon.
Earlier, the army said its forces were locked in fighting with Hezbollah in several sites in southern Lebanon, where a number of soldiers was wounded.
