A senior Iranian military officer said on Saturday that renewed fighting between the U.S. and Iran was "likely", hours after President Donald Trump said he was "not satisfied" with a new Iranian negotiating proposal.

U.S. President Donald Trump said on Friday the U.S. Navy was acting "like pirates" as he described an operation seizing a ship amid the tit-for-tat American blockade of Iranian ports.

"We... land on top of it and we took over the ship. We took over the cargo, took over the oil. It's a very profitable business," Trump said at a rally in Florida.

The United Arab Emirates foreign ministry has announced a travel ban on Emirati nationals going to Iran, Lebanon and Iraq, citing regional developments including the Middle East war.

Iraqi Prime Minister-designate Ali al-Zaidi received a call from U.S. President Donald Trump, who congratulated him on his nomination and invited him to the U.S. once his government is formed, his office announced Thursday.

Tehran's air defenses were activated to counter small aircraft and drones late Thursday, as the White House signalled that it will not be reined in by a congressional deadline on the Iran war.

Israel's defense minister on Thursday said Israel may soon have to "act again" against Iran, to ensure the Islamic republic "does not once again become a threat to Israel."

Iran's President Masoud Pezeshkian on Thursday said a U.S. naval blockade of Iranian ports would deepen disruptions in the Gulf and fail to achieve its objectives.

Iran's supreme leader Ayatollah Mojtaba Khamenei said in a written message on Thursday that the United States had been defeated in its war with the Islamic republic, as the Iranian leadership defied President Donald Trump's warnings of a prolonged blockade.

The leaders of major media companies around the world, including The Associated Press, are calling on Israel's government to lift a ban keeping foreign journalists from being able to independently enter and report from Gaza, a barrier that's been in place since the war's start in 2023 and continues even as a ceasefire has been in place for more than six months.

"Being on the ground is essential. It allows journalists to question official accounts on all sides, to speak directly with civilians and report back what they witness firsthand," said the statement from the executives, released Thursday. "That is why news organizations send their reporters into the field, often at great personal risk."

Israel's foreign ministry said Thursday that Israeli forces had arrested about 175 activists aboard 20 ships from an aid-laden flotilla bound for Gaza.

"Approximately 175 activists from more than 20 boats... are now making their way peacefully to Israel," the ministry said in a statement, including a video of the activists aboard an Israeli navy ship.
