Israel has launched its first attack on the Lebanese capital Beirut since a November ceasefire ended fighting between the Israeli military and Hezbollah.
The IDF warned people to evacuate parts of a Beirut suburb prior to the attacks, vowing to retaliate for strikes they say were launched from Lebanon into Israel.
The Lebanese militant group Hezbollah denied firing any rockets and accused Israel of seeking a pretext to renew attacks.
A Hezbollah source reiterated the group's commitment to the "ceasefire agreement," denying any "connection to the rockets fired today".
The Israeli strike on Beirut marks a significant escalation of conflict in the region.
However, the IDF has since carried out dozens of airstrikes it says target Hezbollah members.
French President Emmanuel Macron called the strikes "unjustified" and said he planned to call both Israel's Prime Minister Benjamin Netanyahu and US President Donald Trump.
Elsewhere in the country, the Lebanese state news agency said an Israeli drone killed two people in the village of Baraachit. Israel's military said that the strike targeted two Hezbollah members.
Another Israeli drone strike in southern Lebanon killed three people, according to the agency. There was no comment from the Israeli military.
Around 14 months of almost daily cross-border fire between Israel and Hezbollah ended last November following a US-brokered ceasefire.
Hezbollah began launching rockets, drones and missiles into Israel the day after the Hamas-led attack on 7 October 2023 that sparked the war in Gaza.
Israeli strikes in Gaza kill Hamas spokesman and family of six
Meanwhile, a family of six and a Hamas spokesperson were killed in separate Israeli strikes in the northern of the Strip overnight into Thursday, Gaza's Hamas-run health ministry said.
A strike hit the tent where Hamas spokesman Abdel-Latif al-Qanou was staying in northern Gaza and killed him, according to the group's official.
Another strike near Gaza City killed four children and their parents, according to local officials.
More than 800 people have been killed by Israel since it broke its ceasefire with Hamas last week.
Israel blamed the renewed hostilities on Hamas' refusal to release more hostages before negotiations on ending the war proceed.
Hamas has said it will only release the remaining captives in exchange for Palestinian prisoners, a lasting ceasefire and the complete Israeli military withdrawal from Gaza.
There are 59 hostages still in captivity in Gaza, with 24 believed to be still alive.
The Hamas incursion into southern Israel left 1,200 people dead and saw 251 others taken hostage.
Meanwhile, the IDF said it stopped two missiles launched by Yemen's Houthi rebels before they crossed into Israeli territory.
Air-raid sirens were heard in Jerusalem, Tel Aviv, central Israel and the West Bank. Local media report that fragments fell in several places but there were no injuries.
The Tehran-backed Houthis claimed responsibility for the attack. They have been attacking Israel and shipping in the Red Sea for over a year in what they say are solidarity attacks with Palestinians in Gaza.
