Iran's military said on Thursday that it had launched a drone attack against a U.S. military site in Kuwait.

"Drone units of the armed force's navy targeted a site of the U.S. forces Camp Udairi in Kuwait using combat drones," the army said in a statement broadcast by state TV.

Iran's Revolutionary Guards said on Thursday they had targeted Israel's Ben Gurion airport and an air force base in the area.

"The heavy Khorramshahr-4 missiles carrying one-ton warheads were launched at dawn today ...  toward the heart of Tel Aviv, Ben Gurion airport and the base of the Israeli air force's 27th squadron located at the airport," the Guards said in a statement carried by Tasnim news agency.

The House is preparing to vote Thursday on a war powers resolution to halt President Donald Trump's attack on Iran, a sign of unease in Congress over the rapidly widening conflict that is reordering U.S. priorities at home and abroad.

It's the second vote in as many days, after the Senate defeated a similar measure along party lines. Lawmakers are confronting the sudden reality of representing the American people in wartime and all that entails — with lives lost, dollars spent and alliances tested by a president's unilateral decision to go to war with Iran.

The Canadian and Australian prime ministers on Thursday called for a de-escalation of the Iran war but added the Iranians must never gain a nuclear weapon.

Canada's Mark Carney and his Australian counterpart Anthony Albanese discussed the war during their meeting in Australia's capital, Canberra.

Iranian state television said Iran had struck a U.S. oil tanker in the Gulf with a missile on Thursday, the latest Iranian attack on the energy industry in the region.

The ship "was hit by a missile in the north of the Persian Gulf" and "is currently on fire", Iran's Revolutionary Guards said in a statement reported by state television.

Iran launched a new wave of attacks Thursday morning at Israeli and American bases and threatened that the United States would "bitterly regret" torpedoing an Iranian warship in the Indian Ocean and a religious leader called for "Trump's blood," while Israel said it had begun a "large-scale" attack on Tehran.

Israel announced multiple incoming missile attacks and air sirens sounded in Tel Aviv and Jerusalem. Iranian state television said additional strikes also targeted U.S. bases. The Israeli military said it launched targeted attacks in Lebanon at the Iranian-backed Hezbollah militant group a "large-scale wave of strikes against infrastructure" in Iran's capital, without elaborating. Explosions were heard in multiple locations in Tehran a short time later.

Iran's armed forces threatened on Wednesday to target Israeli missions worldwide if Israel were to attack Tehran's mission in Lebanon, a military spokesman said.

The Israeli military is planning on at least "one or two" more weeks of strikes on Iran, Israeli media reported on Wednesday, the war's fifth day, while launching a fresh wave of attacks in Lebanon against Tehran-backed Hezbollah militants.

Iran announced that a state funeral for supreme leader Ayatollah Ali Khamenei, which had been planned for Wednesday evening in Tehran, was postponed "in anticipation of unprecedented turnout," state television reported.

"The farewell ceremony for the martyred Imam has been postponed. The new date will be announced later," Iranian television reported on Wednesday after Khamenei was killed in U.S.-Israeli strikes over the weekend.

Iran's Revolutionary Guards said Wednesday they had "complete control" of the crucial Strait of Hormuz and Israel launched fresh strikes on Iranian and Lebanese targets as the Middle East war continued into its fifth day.
