Jerusalem/IBNS: At least eight Israeli soldiers were killed in combat operations in Lebanon on Wednesday, marking the first losses in the force since the Israeli Army crossed the border to target Hezbollah, media reports said.

Earlier in the day, an Israeli army captain, Eitan Itzhak, was killed in action, marking the first Israeli combat loss in its ground operations in Lebanon. 

"The IDF (Israeli army) announced that seven more soldiers have fallen," it said in a statement after announcing the death of a first soldier in Lebanon earlier in the day.

"Captain Eitan Itzhak Oster, aged 22... fell during combat in Lebanon," the military said in a statement.

A military website said Oster was killed on Wednesday.

Meanwhile, Hezbollah said its fighters were engaged in clashes with Israeli troops who had "infiltrated" a southern border village.

The group said earlier it had forced Israeli soldiers to withdraw after they attempted to enter the border village of Adaysseh further northeast.

It was the first time the Iran-backed group admitted that there was fighting on Lebanese soil since the start of an escalation in recent weeks when the Israeli army began pounding south Lebanon and later killed Hezbollah leader Hassan Nasrallah in an air strike.

"This is just the start of the confrontation," Hezbollah spokesman Mohammad Afif told media on a tour in the Lebanese capital's southern suburbs.

"The resistance in the south is at its highest level of readiness," he added, referring to Hezbollah fighters.

The Lebanese army also said Israeli forces had briefly breached the demarcation line between the countries.

"Israeli enemy forces breached the Blue Line by approximately 400 metres (yards) into Lebanese territory" in two areas, "then withdrew a short time later", it said on X.

Earlier Wednesday, the Israeli army called for the evacuation of additional areas in southern Lebanon, telling residents to leave over 20 villages and towns in south Lebanon.
