The Lebanese movement has exchanged near-daily fire with Israeli forces in solidarity with Palestinians since Israel launched its war on Gaza , with repeated escalations during 11 months of the cross-border violence.

Hezbollah said it had bombarded the northern Israeli town of "Kiryat Shmona with a volley of Falaq rockets" early Sunday "in response to the enemy attacks... and particularly the attack" that killed the emergency workers in the Lebanese village of Froun.

On Saturday, Lebanon's health ministry said three emergency responders were killed and two others wounded, one of them critically, in an Israeli strike on Froun.

The ministry said the attack had targeted "a Lebanese civil defence team that was putting out fires sparked by the recent Israeli strikes", while the Israeli army claimed it had killed members of Amal movement in Froun.

Lebanon's civil defence agency said three of its employees were killed in "an Israeli strike that targeted a firefighting vehicle after they had finished a firefighting mission".

Prime Minister Najib Mikati condemned the attack, saying in a statement that "this new aggression against Lebanon is a blatant violation of international laws... and human values".

'Repeated, deliberate'

Hezbollah ally the Amal movement said two of its members were among the killed in Saturday's strike. It said they were killed "while carrying out their humanitarian and national duty defending Lebanon and the south".

The Lebanese health ministry statement condemned the "blatant Israeli attack that targeted a team from an official body of the Lebanese state".

It added that the attack was "the second of its kind against an emergency team in less than 12 hours".

Earlier Saturday, the ministry said two emergency personnel from the Islamic Health Committee were wounded when "the Israeli enemy deliberately targeted" near a fire they were heading to extinguish in south Lebanon's Qabrikha, causing their vehicle to swerve.

On Sunday, Hezbollah said that its fighters had also fired rockets at the Israeli community of Shamir, near Kiryat Shmona.

Hezbollah usually targets military positions in northern Israel.

Hezbollah had announced a string of attacks on Israeli troops and positions near the border on Saturday, including with Katyusha rockets and "explosives-laden drones", in a response to "Israeli enemy attacks" on south Lebanon.

The cross-border violence has killed some 614 people in Lebanon, including 138 civilians, according to an AFP tally.

On the Israeli side, including in the occupied Syrian Golan Heights, Tel Aviv have announced the deaths of 24 soldiers and 26 civilians.

A statement from Lebanese Health Minister Firass Abiad said that "due to the (Israeli) aggression", 27 emergency personnel and health workers have been killed and 94 others wounded since October.

Two hospitals and 21 health centres have been "targeted", while 32 fire or ambulance vehicles have been "put out of service or partially damaged", the statement said, urging an end to the "repeated and deliberate targeting of health workers and civilians".
