The Israeli army said Tuesday it had struck around 10 Hezbollah targets overnight in seven different areas of south Lebanon, killing one fighter from the Iran-backed militant group.
The army also "struck a Hezbollah weapons storage facility, terror infrastructure sites, military structures and a launcher in southern Lebanon", the army said, AFP reported.
The strikes came after a rocket fired from Lebanon hit a Druze Arab town in the Israeli-annexed Golan Heights on Saturday and killed 12 children aged between 10 and 16.
On a visit to Majdal Shams on Monday, Prime Minister Benjamin Netanyahu vowed Israel would deliver a "severe response" to the strike.
Israel says the rocket that killed the children was an Iranian-made Falaq and was fired by its ally Hezbollah.
Hezbollah has denied responsibility for firing the rocket though it claimed multiple launches towards Israel on Saturday.
Israeli forces and Hezbollah have been engaged in near-daily clashes along the border since the start of the Israel-Hamas war on October 7.
The violence has so far killed 22 soldiers and 24 civilians on the Israeli side, including in the Golan, according to army figures.
