Lebanon’s Hezbollah infrastructure north of Baalbek in eastern Lebanon amid concerns that increased exchanges of fire between Israel and Hezbollah could fuel further escalation.

“Earlier this evening, IAF fighter jets struck significant Hezbollah terrorist infrastructure used by the terrorist organization’s aerial defense system in northern Baalbek,” the statement said.

This attack comes shortly after Hezbollah launched missiles and drones at a military facility in northern Israel in retaliation for Israeli strikes that killed Hezbollah members, an incident that the Israeli military said left 14 soldiers wounded.

The Israeli 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 center in the village.

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.

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.

At least 370 Lebanese, including more than 240 Hezbollah fighters and 68 civilians, have been killed in the fighting according to a Reuters tally. Eighteen Israelis, including soldiers and civilians, have been killed.
