The Lebanese group said in a statement that it fired "dozens of Katyusha and Falaq rockets" at Kiryat Shmona in northern Israel "in response to the horrific crime that the Israeli enemy committed in Mays al-Jabal" which it said killed and wounded civilians.

The Israeli army said that a barrage of some 65 rockets were fired from Lebanon at the Galilee Panhandle. Some of the rockets were intercepted, according to the military.

There are no reports of injuries in the attack. It marks one of the largest barrages carried out from Lebanon amid the war on Gaza.

Israel and Lebanon's Hezbollah resistance group have exchanged regular cross-border fire since the war on Gaza began.

Fighting has intensified in recent weeks, with Israel striking deeper into Lebanese territory, while Hezbollah has stepped up its missile and drone attacks on military positions in northern Israel.

Lebanon's state-run National News Agency said the strike in Mais al-Jabal killed "four people from a single family", updating an earlier reported toll of three dead in the raid it said was carried out by Israeli aircraft.

It identified them as a man, a woman and their children aged 12 and 21, and said two other people were wounded.

A Lebanese security source, requesting anonymity as they were not authorised to speak to the media, confirmed the strike killed "four civilians".

Mais al-Jabal municipality chief Abdelmoneim Shukair had earlier told AFP that three people were killed, saying they were a couple and their son.
