Hezbollah on Friday released a video showing what appeared to be underground tunnels and large missile launchers, amid fears of all-out war between the Iran-backed group and Israel.

The release comes as negotiators seeking a Gaza ceasefire were to meet for a second day in Qatar, and amid intensified diplomatic activity in Lebanon seeking to avert a broader conflict.

Ten months of cross-border violence between Hezbollah and Israeli forces has killed senior commanders and several hundred fighters from the Iran-backed group, causing destruction and displacing tens of thousands on both sides.

Hezbollah has seen more fighters killed since October than when it last went to war with Israel in the summer of 2006.

Israeli firefighters Thursday were battling back blazes ignited by rockets from Lebanon, fire officials said.

Five trucks of firefighters spent the afternoon putting out a fire in the Upper Galilee, near Kibbutz Shamir, Israeli fire spokesperson Isaac Ben-David told The Associated Press.

France’s top diplomat Thursday met with top Lebanese officials in Beirut, as the region anticipates a retaliatory attack on Israel from Iran and Hezbollah and as negotiations for a cease-fire in the war-torn Gaza Strip recommenced in Qatar.

“We are all concerned about the regional situation. Our message is simple which is de-escalation,” said French Foreign Minister Stéphane Séjourné following a meeting with Parliament Speaker Nabih Berri.

Parliament Speaker Nabih Berri has said that U.S. mediator Amos Hochstein's visit to Lebanon on Wednesday has created "positivities that can be capitalized on."

Lebanon's health ministry said Israeli strikes killed two people in the country's south on Wednesday, with Hezbollah announcing the deaths of two of its fighters, the latest cross-border violence amid fears of a full-blown regional war.

Hezbollah has traded near daily fire with the Israeli army since the Palestinian militant group Hamas' unprecedented October 7 attack on Israel triggered the Gaza war.

Seventeen people were wounded, four of them critically, when an Israeli airstrike targeted the intersection of the southern town of al-Abbasiyeh near Tyre on Wednesday, the Health Ministry said.

Another strike meanwhile targeted a house in the southern border town of Rab Tlatine.

Caretaker Prime Minister Najib Mikati on Wednesday stressed to visiting U.S. mediator Amos Hochstein “the need to press Israel to halt its attacks and threats,” noting that “the gateway for the solution is a ceasefire in Gaza and the implementation of U.N. Security Council resolutions, especially Resolution 1701.”

Air France and its Transavia subsidiary expect to resume service to Beirut Thursday, which has been suspended since July 29 because of tensions in the Middle East, the French carrier said Wednesday.

"At this stage, and subject to the evolution of the security situation at destination, the airline plans to resume its flights between Paris-Charles de Gaulle and Beirut on Thursday, August 15, 2024," Air France said in a communique.

Visiting U.S. envoy Amos Hochstein warned Wednesday that the clock was ticking for a Gaza ceasefire that would also end 10 months of cross-border exchanges between Lebanon's Hezbollah and Israel.

Hochstein told a Beirut news conference that he and Parliament Speaker Nabih Berri, a Hezbollah ally, discussed "the framework agreement that's on the table for a Gaza ceasefire, and he and I agreed there is no more time to waste and there's no more valid excuses from any party for any further delay."
