The military said six of the soldiers were in serious condition. It said it “struck the sources of fire” after identifying several anti-tank missile and drone launches from Lebanon towards the Bedouin village of Arab al-Aramshe.
The Israeli Ynet news site said the soldiers were in a community centre in the village.
On Tuesday, Israeli strikes in southern Lebanon killed three people, including a Hezbollah field commander, Lebanese security sources said.
Israeli forces and Lebanon’s armed group Hezbollah have been exchanging fire for over six months in parallel to the Gaza war, in the most serious hostilities since they fought a major war in 2006.
Later on Wednesday, Israel’s air force said its fighter jets struck Hezbollah infrastructure north of Baalbek in eastern Lebanon, reaching beyond the southern border region where Israel has focused most of its strikes.
The fighting has fuelled concern about the risk of further escalation. Those concerns have mounted following Iran’s retaliatory attack on Israel, with hundreds of explosive drones, cruise missiles and ballistic missiles launched on Saturday night, to which Israeli officials have vowed to respond.
