Israel-Gaza live updates: Israel moves troops to Lebanon border after pager attack

In a Wednesday morning statement, the Hezbollah militant group said it would continue operations to "support Gaza" and vowed a "reckoning" for Israel after Tuesday's "massacre" when more than 2,750 people were injured by exploding pagers in Lebanon.

Hezbollah blamed Israel for the operation, which killed at least nine civilians. Eleven Hezbollah members died on Tuesday, the group said, though -- as is typical in its statements -- did not specify how they died.

Hezbollah leader Hassan Nasrallah is set to speak on Thursday afternoon to address the situation.

Israel has not commented on its alleged involvement in Tuesday's explosions in Lebanon.

Benny Gantz -- the leader of the centrist National Unity coalition -- on Tuesday accused rival Prime Minister Benjamin Netanyahu of endangering Israeli security "in the most tangible way that I can remember being done by a prime minister during a war, and in general."

In a public statement -- later also published on his X page -- Gantz accused the prime minister of "security recklessness" over reports that Netanyahu is preparing to replace Defense Minister Yoav Gallant, who is a major critic of the prime minister's approach to cease-fire negotiations in Gaza.

Gantz said the alleged political maneuvering is particularly dangerous ahead of a potential expansion of the conflict in the north of the country, where the Israel Defense Forces has been engaged in cross-border fighting with the Iran-backed Lebanese Hezbollah militia since Oct. 8.

"Human lives and the future of the nation are at stake," Gantz said, describing the situation as the "dictionary definition of petty politics, at the expense of national security."
