Iran's Supreme National Security Council on Tuesday confirmed the death of its chief Ali Larijani, after Israel said it had killed him in an air strike.

U.S. President Donald Trump, whose call for assistance from allies to reopen the Strait of Hormuz to oil traffic has largely been rebuffed, said Tuesday that U.S. forces "no longer need" military help in the Iran war.

"Because of the fact that we have had such Military Success, we no longer 'need,' or desire, the NATO Countries' assistance -- WE NEVER DID! Likewise, Japan, Australia, or South Korea," Trump posted on his Truth Social network, adding: "WE DO NOT NEED THE HELP OF ANYONE!"

Falling debris from missile interceptions killed one person on Tuesday in the Emirati capital of Abu Dhabi and injured two medical staff in Kuwait, authorities said, as Iran pressed its attacks against Gulf countries.

Joe Kent, the director of the National Counterterrorism Center, announced his resignation on Tuesday, saying he "cannot in good conscience" back the Trump administration's war in Iran.

Kent said on social media Iran "posed no imminent threat to our nation, and it is clear that we started this war due to pressure from Israel and its powerful American lobby."

The U.N. human rights chief's office expressed concerns about possible "ethnic cleansing" in a new report on Tuesday, saying that Israel has accelerated the expansion of settlements in large parts of the occupied West Bank and the forced displacement of more than 36,000 Palestinians.

The report from the office of Volker Türk, the U.N. high commissioner for human rights, covers a yearlong period through the end of October. It decries increased violence by Israeli settlers and security forces against Palestinians in the area.

Israeli Defense Minister Israel Katz said on Tuesday that Iran's powerful national security chief Ali Larijani was "eliminated last night", along with the commander of Tehran's Basij paramilitary force.

"I have just been updated by the Chief of Staff that Larijani, Secretary of the Supreme National Security Council, and the head of the Basij -— Iran's central repression apparatus -— (Soleimani), were eliminated last night," Katz said in a statement released by his ministry.

Israel said Tuesday it had killed the head of the Iranian Revolutionary Guards' all-volunteer Basij force, a key force used to suppress demonstrations in the Islamic Republic, as Gulf Arab nations came under renewed missile and drone fire from Iran.

Dubai, a major transit hub for international travel, briefly shut its airspace as the military said it was "responding to incoming missile and drone threats" around the city, and a man was killed by the debris of a missile intercepted over Abu Dhabi.

NATO allies and other Western nations pushed back Monday on U.S. President Donald Trump's demand that military alliance members help reopen the Strait of Hormuz, the critical conduit for crude oil Iran has effectively closed.

European countries on Monday demanded to know more about U.S. President Donald Trump's plans for the war on Iran and when the conflict might end as they weighed whether to agree to his call to send warships to help shore up security in the Persian Gulf.

Trump has asked allies — including France, China, Japan, South Korea and Britain — to help secure the strait for global shipping. He said the U.S. was talking to "about seven" countries for military support to help reopen the trade route. But he wouldn't say which ones and gave no indication of when such a coalition might be formed.

At least 12 Palestinians, including two boys, a pregnant woman and eight police officers, were killed Sunday by Israeli airstrikes in the war-torn Gaza Strip, hospital authorities said.

A strike Sunday morning hit a house in the urban refugee camp of Nuseirat in central Gaza and killed four people, including a couple in their 30s and their 10-year son, according to the nearby Al-Aqsa Martyrs Hospital. The woman had been pregnant with twins, the hospital said.
