Lebanon’s state-run National News Agency (NNA) reported that Israeli warplanes carried out strikes in at least 11 areas of southern Lebanon on Monday night.
They included the town of Haris, where the health ministry said six people were killed and two injured.
Another four people were killed and one was injured in the town of Tallousseh, according to the ministry.
The Israeli military said in a statement that it “struck Hezbollah terrorists, dozens of launchers, and terrorist infrastructure throughout Lebanon”.
It also said it hit the Hezbollah launcher in Berghoz that was used to fire two mortars towards the disputed Mount Dov/Shebaa Farms area in the occupied Golan Heights. The projectiles fell in an open area and nobody was hurt.
“Hezbollah’s launches tonight constitute a violation of the ceasefire agreement between Israel and Lebanon,” it warned.
“The State of Israel demands that the relevant parties in Lebanon fulfil their responsibilities and prevent Hezbollah's hostile activity from within Lebanese territory.”
Israel‘s Prime Minister, Benjamin Netanyahu, said it was “determined to continue enforcing the ceasefire and will respond to every Hezbollah violation - minor and major”.
Hezbollah confirmed it carried out the mortar attack, saying it was a “defensive and warning response” to what it described as “repeated violations by the Israeli enemy of the ceasefire agreement”.
It said they included firing on civilians and conducting air strikes, as well breaches of Lebanese airspace by Israeli aircraft.
Earlier on Monday, Lebanese authorities said two people had been killed in Israeli strikes in the south of the country.
The health ministry said one person was killed in Marjaoun, where a motorcycle was reportedly targeted, while Lebanese State Security agency said a drone strike killed one of its personnel who was on duty in Nabatieh.
The Lebanese army also said a soldier was wounded when a drone targeted an army bulldozer near the north-eastern town of Hermel, in the Bekaa Valley.
The Israeli military said it had “operated in southern Lebanon in response to several acts by Hezbollah in Lebanon that posed a threat to Israeli civilians, in violation of the understandings between Israel and Lebanon”.
“We are aware of reports regarding a soldier from the Lebanese military who was injured in one of the strikes and the incident is under investigation,” it added.
