The IDF said more than 100 projectiles crossed into Israel from Lebanon.
Hezbollah launched more than 100 projectiles into Israel on Tuesday morning as the Israel Defense Forces continued its intense air and ground campaign in Lebanon.
The latest exchanges of fire came one day after Israel marked the anniversary of Hamas' Oct. 7 assault and as Israeli leaders planned their response to last week's Iranian ballistic missile attack.
Hanan Balkhi, the regional director of the World Health Organization Eastern Mediterranean Regional Office, said Tuesday that 77 health workers have been killed and 74 others wounded by Israeli attacks since the beginning of October.
Health infrastructure has been "severely damaged," the WHO wrote on X, with the organization verifying 36 attacks on health facilities so far in October.
Hezbollah Deputy Secretary-General Naim Kassem said Tuesday that the Iran-backed group will not be cowed by Israel's ongoing air and ground campaign in Lebanon.
"The longer the war goes on, the deeper Israel will find itself in trouble," Kassem said in a video address delivered from an unknown location. Prime Minister Benjamin Netanyahu "can say that he wants war, but he cannot achieve his goals from it," he added.
More Israelis in the north of the country will be displaced as Hezbollah expands its operations, he said.
Hezbollah will continue cross-border attacks and "expanding the range of the missiles," the leader said.
"This war has not affected our will and will not affect our determination to confront," Kassem said. "Our resistance on the front is cohesive and the administration is cohesive."
"Our resources and capabilities remain in good shape," Kassem said, despite weeks of intense Israeli airstrikes across Lebanon. "Our command and control is solid. Look at how our operations have increased in the last few days." Still, Kassem also said Hezbollah supports Lebanese government efforts to secure a cease-fire.
Kassem said the U.S. bears responsibility for the ongoing war. "Israel and America and the West are trying to put more pressure on us to make us afraid," he continued.
"Without American support, the Israeli aggression would have stopped within a month," Kassem said.

Hezbollah launched a barrage of rockets into northern Israel on Tuesday as the group's Deputy Secretary-General Naim Kassem issued a defiant address vowing to defeat Israel's operations in Lebanon.
The Israel Defense Forces said 135 projectiles were fired into Israeli territory, some of which were intercepted and some of which landed.
The launches prompted sirens in the city of Haifa and elsewhere in the north of the country.
In his video address, Kassem -- Hezbollah's acting leader -- said more Israelis will displaced in the north of the country as the militant group expands its rocket fire deeper into Israel.
Kassem said Hezbollah's capabilities are still intact despite weeks of heavy Israeli airstrikes. He added that the group has replaced all commanders killed by Israeli attacks.

Former Israeli Prime Minister Naftali Bennett called for a major attack on Iran, saying in a video posted to social media on Tuesday: "The opportunity must not be missed."
Israeli leaders say they are preparing a response to Iran's Oct. 1 ballistic missile barrage.
"Attack the Iranian nuclear program and the regime centers now," urged Bennett, who was prime minister from 2021 to 2022 and remains an influential voice in national politics.
An August poll by Israel's Channel 12 news found 38% of respondents would support Bennett's return as prime minister, versus 33% who wanted Netanyahu to remain in the post. Both men polled better than opposition leaders Benny Gantz and Yair Lapid.
