The strikes on roads and bridges come as Israel's military says it is sending more forces to the front along the border with Lebanon.

Prime Minister Nawaf Salam warned Friday that Lebanon is "facing one of the most dangerous chapters in its modern history."

"The truth is, this is a conflict they (Lebanese people) did not choose and did not want. In the past few weeks, as hostilities intensified, more than 900,000 people—nearly one in five residents—have been forced to flee their homes and seek refuge across Lebanese territory," said Salam in a speech at the Grand Serail during the launch of the "2026 Emergency Humanitarian Appeal for Lebanon," in the presence of U.N. chief Antonio Guterres, U.N. officials and foreign ambassadors.

The Israeli military said on Friday it had carried out around 7,600 strikes in Iran and 1,100 in Lebanon since launching its joint operation with the United States against Tehran.

In Lebanon, it said it had struck 200 "missile and launcher targets" and around 35 command-and-control sites of the Iran-backed Hezbollah group, and killed "more than 380 Hezbollah terrorists".

Speaker Nabih Berri on Friday reaffirmed to visiting U.N. chief Antonio Guterres Lebanon's commitment to U.N. Resolution 1701, stressing that "there is no alternative to the UNIFIL force for implementing it in ccordination with the Lebanese Army."

Iran's Revolutionary Guards announced on Friday that they had launched missiles and drones at Israel in coordination with Lebanese Hezbollah.

The Guards said in a statement that the operation was part of its annual Quds Day, which is intended to show support for the Palestinian cause.

Lebanese Forces leader Samir Geagea said Friday in an interview with Al-Arabiya's Al-Hadath channel that "Hezbollah is an Iranian faction present in Lebanon."

Israeli strikes have killed at least 773 people since March 2, the Lebanese health ministry said on Friday, as Israel vowed that Lebanon will pay an "increasing price" in damage to infrastructure.

"The total number of martyrs from March 2 to March 13 reached 773, and the number of wounded reached 1,933" including 103 children, the ministry said in its daily update.

President Joseph Aoun said Friday he had not received a response to his offer to negotiate directly with Israel to try to halt its war with Hezbollah in Lebanon.

Lebanon was drawn into the Middle East war last week when Iran-backed Hezbollah attacked Israel in response to the killing of Iranian supreme leader Ayatollah Ali Khamenei in U.S.-Israeli strikes.

Israeli planes dropping propaganda leaflets over Beirut on Friday caused a number of loud booms in the sky, terrifying residents of the Lebanese capital.

AFP correspondents heard four successive booms at short intervals, before clouds of paper leaflets appeared high in the air.

Israeli Defense Minister Israel Katz said Friday the strikes on Lebanon so far were "just the beginning" and warned that Lebanon will suffer increasing damage to its infrastructure, after the Israeli army targeted a bridge over the Litani river that it said Hezbollah had been using as a passageway for its fighters.

"This is just the beginning and the Lebanese government, and the State of Lebanon will pay an increasing price in damage to Lebanese national infrastructure used by Hezbollah terrorists due to terrorist activity and launches at the State of Israel," Katz said at a meeting with army top brass.
