Israel’s military on Tuesday said it had expanded its “limited, localised, targeted operations” into southwestern Lebanon, before Hezbollah fired over a hundred rockets at Israeli city of Haifa in an hour, CNN reported.

While numerous rockets were intercepted or fell in open areas, according to the military, at least two buildings in Kiryat Yam and Kiryat Motzkin were directly hit.

Shortly after the rocket barrage, Israel Defense Forces (IDF) announced its 146th Division targeted operational activities against Hezbollah targets and infrastructure in southwestern Lebanon.

“The 146th Division is the first reserve division to operate in southern Lebanon as part of the ongoing operations against Hezbollah in the northern arena,” the IDF said, adding that the division “has served as a defensive regional brigade and its forces were deployed in northern Israel, the Gaza Strip” and the occupied West Bank.

The division will be working alongside the 213th Artillery Brigade.

The Israeli military’s ground incursion in southern Lebanon, which began a week ago, had been focused on the eastern part of the border area.

Earlier, the Israeli military claimed that it killed the commander of Hezbollah’s headquarters, Suhail Hussein Husseini, in “the area of Beirut.”

CNN was unable to independently verify the claim, how senior in Hezbollah Husseini is, and what role he played. Hezbollah has yet to confirm whether Husseini has been killed.

Husseini, according to the Israeli military, played a role in “weapon transfers between Iran and Hezbollah and was responsible for distributing the advanced weaponry among Hezbollah’s units,” and he also was a “member of the Jihad council, Hezbollah’s senior military leadership council.”
