Hezbollah said two of its fighters were "martyred on the road to Jerusalem."
The Israeli occupation army said air forces struck Hezbollah fighters in the Hula area and "Hezbollah military structures" elsewhere in south Lebanon.
Lebanon's official National News Agency (NNA) reported Israeli shelling and raids on several southern areas, and said "enemy warplanes broke the sound barrier twice over Beirut and its suburbs... at low altitude".
Hezbollah said it launched a "simultaneous air attack" with "explosive-laden drones" on two Israeli military positions -- the Yaara barracks near the border, and a base near the coastal town of Acre, around 15 kilometres (10 miles) from the frontier.
Israel said in a statement that "multiple suspicious aerial targets were identified crossing from Lebanon".
Israeli air defences "intercepted some of the targets, and others fell" in the Yaara area, the statement added.
Hezbollah said that attack came "in response" to an Israeli "attack and assassination" in south Lebanon's Tyre area.
Imran Riza, the United Nations humanitarian coordinator in Lebanon, said in a statement that "nearly 150,000 people continue to live in areas impacted daily by shelling and airstrikes" in Lebanon.
"Millions more are reliving painful memories of the 2006 war, traumatised by worry over the risk of further escalation," he said, referring to the last major conflict between Israel and Hezbollah.
According to the UN's International Organization for Migration, the violence since October has displaced more than 110,000 people in south Lebanon.
Riza added that "21 paramedics whose duties were to save others have been killed", saying "the seeming impunity with which such actions have been committed reveals a troubling disregard for international humanitarian law".
The cross-border violence has killed some 584 people in Lebanon, including at least 128 civilians, according to an AFP tally.
On the Israeli side, including in the occupied Syrian Golan Heights, 22 soldiers and 26 residents have been killed, according to army figures.
