MOSCOW, March 7 (Reuters) - Russian President Vladimir Putin expressed his condolences to Iran's president over the numerous civilian casualties resulting from "the armed Israeli-American aggression against Iran" and called for an immediate halt to hostilities, the Kremlin said.

In a phone call late on Friday with Iranian President Masoud Pezeshkian, Putin expressed his deep condolences over the killing of Iranian Supreme Leader Ayatollah Ali Khamenei, members of Khamenei's family, Iranian political and military leaders and "numerous civilians".

WASHINGTON, March 7 (Reuters) - One week into the U.S.-Israeli war against Iran that has plunged the Middle East into turmoil, President Donald Trump faces a growing list of risks and challenges that raise questions about whether he will be able to translate military successes into a clear geopolitical win.

Gulf nations reported on Sunday missiles and drone attacks, while Iran vowed to press on with strikes against neighbouring countries as the regional war entered its second week.

Saudi Arabia, Qatar and Kuwait all reported new attacks, after loud explosions were heard in Dubai and Bahrain's Manama a day earlier, and Kuwait's national oil company announced a "precautionary" cut to production.

An Israeli special forces operation that failed to find the remains of airman Ron Arad, captured in Lebanon in 1986, killed 41 people and wounded 40 in eastern Lebanon.

Gutted buildings, torn-off roofs, munitions scattered on the ground surrounded a large crater in Nabi Sheet, the town that witnessed the operation which involved air strikes and clashes.

"The sounds of the explosions were like something out of a movie," Nabi Sheet resident Mohammed Mussa, 55, told AFP during a media tour organised by the Iran-backed group Hezbollah.

Donald Trump has plunged the United States into its most significant conflict in decades over a "feeling." It's not his political opponents saying this, but the White House itself.

Throughout the first week of the war with Iran, the US president has prioritized impulse and emotion over explanations and reasoning.

"I hope you're impressed," Trump, a former reality TV host, told an ABC News reporter on Thursday. "How do you like the performance?"

The latest bout of fighting between the United States, Israel and Iran has seen AI deployed as never before to sift intelligence and select targets, although the technology's use in war remains hotly debated.

Different forms of artificial intelligence have reportedly been used to guide the Israeli campaign in Gaza and the capture of Venezuelan leader Nicolas Maduro in an American raid.

And experts believe the technology has helped select targets for the thousands of US and Israeli strikes on Iran since February 28 -- although exact uses have yet to be confirmed.

WASHINGTON, March 6 (Reuters) - The U.S. State Department said on Friday it has made a determination approving a possible foreign military sale to Israel of munitions and munitions support for $151.8 million, without congressional review.

Israel has requested to buy 12,000 BLU-110A/B general purpose, 1,000-pound bomb bodies, the State Department said in a statement.

Secretary of State Marco Rubio determined that an emergency existed that required the immediate sale to Israel. The announcement comes during the U.S. and Israel's war against Iran.

A Pakistani man with alleged ties to Iran was found guilty Friday of plotting to assassinate President Donald Trump or other US officials in retaliation for the American military killing of Revolutionary Guards commander Qassem Soleimani, prosecutors said.

Asif Raza Merchant allegedly sought to hire a hitman to assassinate a politician or a government official in the United States, prosecutors established during the trial in a federal court in Brooklyn.

March 6 (Reuters) - Iran's U.N. ambassador Amir Saeid Iravani on Friday said at least 1,332 Iranian civilians had lost their lives so far in the conflict with Israel and the United States and thousands more had been injured.

He made his comments while speaking to reporters at the United Nations in New York.

PARIS, March 6 (Reuters) - European Union member states that jointhe U.S. and Israel attacks on Iran would become "legitimate targets" for Iran, Deputy Foreign Minister Majid Takht-Ravanchi said in an interview with TV station France 24.

"Any country that joins in the aggression against Iran, joins America and Israel in the aggression against Iran, definitely, they will be also legitimate targets for Iran retaliation," Takht-Ravanchi said.
