In a statement, Hezbollah said its fighters had targeted a deployment of Israeli soldiers in the vicinity of the Al-Marj military site.
The Israeli public broadcaster KAN said eight Israelis were injured, including two in serious condition, by two anti-tank missiles fired from Lebanon at the Upper Galilee area.
Separately, the Israeli army said its fighter jets carried out overnight raids across southern Lebanon, claiming to have struck Hezbollah buildings and military infrastructure.
According to a military statement, the warplanes struck what it called military buildings used by Hezbollah in the southern towns of Chihine, Blida, Mays al-Jabal, Aitaroun, and Kfar Kela.
It added that a Hezbollah weapons depot was also struck by a drone in the town of Khiam.
Israel remains on high alert in anticipation of a response from Hezbollah following two waves of communication device blasts on Tuesday and Wednesday that killed dozens of Lebanese across Lebanon and injured thousands, including Hezbollah members.
The blasts came amid an escalation in cross-border warfare between Israel and Hezbollah since the start of Israel’s deadly war on the Gaza Strip, which has killed over 41,200 people, mostly women and children, following a cross-border attack by Hamas last Oct. 7.
