Hezbollah said Sunday that it targeted an Israeli military vehicle across the border with guided missiles, killing and wounding its crew members.

The Israeli military confirmed in a statement that an antitank missile was launched from Lebanon at Yiftah in northern Israel, and said it was striking the sources of fire. It did not confirm whether there were casualties.

Israel’s minister of Jewish heritage, Amihai Eliyahu, said Sunday that dropping an atomic bomb on the Gaza Strip is a possibility. His comments were immediately denounced by other Cabinet members.

Eliyahu, a junior minister in Prime Minister Benjamin Netanyhau’s Cabinet, made the comment in an interview with Kol Beramah radio. He later tried to walk it back, saying, “Anyone reasonable would understand that the comment was metaphorical. But we definitely need to respond powerfully and disproportionately to terrorism."

Caretaker Prime Minister Najib Mikati and Egyptian President Abdel Fattah al-Sisi have urged the international community to intensify efforts to "contain the situation" between Israel and the Palestinians and avert expanding the scope of violence."

Mikati flew to Cairo on Saturday for talks with al-Sisi after his meeting with U.S. Secretary of State Antony Blinken in the Jordanian capital of Amman.

U.S. Secretary of State Antony Blinken thanked caretaker Prime Minister Najib Mikati during their meeting in Jordan for his leadership “in preventing Lebanon from being pulled into a war that the Lebanese people do not want,” the U.S. State Department said.

Mikati for his part stressed “the priority of working for a ceasefire in Gaza to halt the continuous Israeli aggression there, and also working on stopping the Israeli aggression against south Lebanon,” Lebanon’s National News Agency said.

Israeli warplanes conducted airstrikes along the border with Lebanon Saturday after Hezbollah attacked several Israeli army posts.

The escalation came a day after Hezbollah leader Sayyed Hassan Nasrallah said his powerful group is already engaged in unprecedented fighting along the Lebanon-Israel border. He threatened a further escalation as Israel's war in Gaza with Hamas, Hezbollah's ally, nears the one-month mark.

Arab leaders decrying the deaths of thousands of Palestinian civilians in the Israel-Hamas war pushed for an immediate cease-fire Saturday even as U.S. Secretary of State Antony Blinken warned that such a move would be counterproductive and could encourage more violence by the militant group.

After an afternoon of talks with Egyptian, Jordanian, Saudi, Qatari and Emirati diplomats and a senior Palestinian official, Blinken stood side by side at a line of podiums with his counterparts from Jordan and Egypt to discuss what he said was their shared desire to protect civilians in Gaza and improve aid flows to the besieged territory.

Thousands of Israelis protested outside Prime Minister Benjamin Netanyahu’s official residence in central Jerusalem, calling on the Israeli leader to resign in the wake of the bloody Oct. 7 Hamas rampage that sparked the latest Israel-Hamas war.

Netanyahu has so far refused to take responsibility for the Oct. 7 attack, in which hundreds of Hamas militants burst into Israel and allegedly killed over 1,400 people and took some 240 hostages back to Gaza. He says officials, including himself, will have to give answers to the public, but only after the war.

Israeli warplanes struck a refugee camp in the Gaza Strip early Sunday, killing at least 33 people and wounding dozens, health officials said. The strike came as Israel said it would press on with its offensive to crush the territory's Hamas rulers, despite U.S. appeals for a pause to get aid to desperate civilians.

The soaring death toll in Gaza has sparked growing international anger, with tens of thousands from Washington to Berlin taking to the streets Saturday to demand an immediate cease-fire.

Julia Norman, an associate professor of politics and international relations at University College London, has said that both U.S. Secretary of State Antony Blinken and Hezbollah chief Sayyed Hassan Nasrallah -- two actors who “are going to be very influential on how the conflict moves from this point” -- have both offered signals Friday against a wider war.

“That’s not to say it won’t, but the messaging today from both seemed to be ... trying to operate within a sense of restraint and to not have this ripple out even further,” she said.

Palestinians in Gaza reported Israeli airstrikes overnight into Saturday across the besieged enclave, including the southern part where Israel had told civilians to seek refuge as its ground operation intensifies in northern Gaza.

Raed Mattar, who had fled northern Gaza early in the war and is sheltering in a school in the southern town of Khan Younis, said he heard explosions, apparently from airstrikes.
