Iranian and American forces were racing each other early Saturday to recover a crew member of the first US fighter jet to go down inside Iran since the start of the war.

Tehran said it had shot down the F-15 warplane, while US media reported American special forces had rescued one of its two crew members, with the other still missing.

Iran's military also said it downed a US A-10 ground attack aircraft in the Gulf, with US media saying the pilot was rescued.

WASHINGTON/BRUSSELS/PARIS, April 3 (Reuters) - The NATO alliance has in recent years survived existential challenges - ranging from the war in Ukraine to multiple bouts of pressure and insults from U.S. President Donald Trump, who has questioned its core mission and threatened to seize Greenland.

But it is the U.S.-Israeli war with Iran, thousands of miles from Europe, that has nearly broken the 76-year-old bloc and threatens to leave it in its weakest state since its creation, say analysts and diplomats.

WASHINGTON/CAIRO, , April 3 (Reuters) - President Donald Trump said the U.S. "hasn't even started destroying what's left in Iran", reiterating vows to increase the ferocity of attacks on its infrastructure, as dozens of countries sought ways to restart vital energy shipments through the Strait of Hormuz.

Nearly five weeks after it started with a joint U.S.-Israeli aerial assault, the war in Iran continues to spread chaos across the region and roil financial markets, raising the pressure on Trump to find a quick resolution to the conflict.

WASHINGTON, April 2 (Reuters) - U.S. President Donald Trump warned late on Thursday about striking and destroying bridges and electric power plants in Iran in his latest threat to hit the country's infrastructure.

The U.S. military "hasn't even started destroying what's left in Iran. Bridges next, then Electric Power Plants," Trump wrote on social media.

His post said that Iran's leadership "knows what has to be done, and has to be done, FAST!"

April 2 (Reuters) - The U.N. Security Council is to vote on a Bahraini resolution to protect commercial shipping in and around the Strait of Hormuz, diplomats said on Friday, but veto-wielding China made clear its opposition to authorizing any use of force.

Two diplomats said the meeting of the Council's 15 members and the vote were set for Saturday morning, rather than Friday as earlier planned. Friday is a U.N. holiday.

Israeli filmmaker Nadav Lapid thinks sometimes movies can change history; other times they simply narrate it.

With his latest production, which hits US theaters Friday, the filmmaker has set himself a different goal.

"I hope 'Yes' shakes people's souls," he said.

The chaotic satire -- which premiered in Europe last year -- follows musician Y (Ariel Bronz) and dancer Yasmin (Efrat Dor), a young couple in Tel Aviv who raise their newborn son during the day, while entertaining at wild fetish parties for the wealthy by night.

The UN Security Council has postponed a vote scheduled for Friday on authorizing the use of "defensive" force to protect shipping in the Strait of Hormuz from Iranian attacks, according to the official program.

The 15-member body was set to vote Friday morning on a draft resolution brought by Bahrain, but by Thursday night the schedule shifted.

The reason given was that the United Nations observes Good Friday as a public holiday, according to diplomatic sources -- despite this fact being known when the vote was first announced.

WASHINGTON, April 2 (Reuters) - Dozens of international law experts in the U.S. have signed an open letter saying that American strikes on Iran may amount to war crimes, after President Donald Trump reiterated his threats this week to strike Iran's power and desalination plants.

Trump, who has previously offered shifting timelines and objectives for the war, said in a televised speech on Wednesday that the war could escalate if Iran did not give in to Washington's terms, with strikes on its energy and oil infrastructure possible.

Threatening to destroy Iran's electricity grid and to reduce the country of 90 million to destitution, US President Donald Trump is shattering precedent by not just accepting but gloating about acts seen as potential war crimes.

The consequences for Trump, at least in the near term, are probably none, experts say, as his administration works hard to undermine international institutions tasked with keeping norms.

April 2 (Reuters) - President Volodymyr Zelenskiy on Thursday offered to provide Ukraine's expertise in dealing with freedom of navigation in the Black Sea to countries considering how to keep the Strait of Hormuz open amid conflict in the Middle East.

Zelenskiy, speaking in his nightly video address, said Foreign Minister Andrii Sybiha had taken part in a virtual meeting devoted to reopening the Strait of Hormuz, attended by about 40 countries.

"Ukraine has relevant expertise concerning sea waterways, concerning the defence and reopening of maritime traffic," he said.
