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.
