U.S. President Donald Trump on Wednesday again signaled there could be a swift ending to the U.S. war on Iran, saying there is little left in the country for U.S. forces to attack.

There is "practically nothing left to target" and the war will end "soon," Trump was quoted as saying in an interview with Axios. "Any time I want it to end, it will end."

In New York, around 30 countries backing the U.N. peacekeeping force in Lebanon voiced concern over the fighting in Lebanon, which was drawn into the war last week when militant group Hezbollah attacked Israel in response to the killing of Iranian supreme leader Ayatollah Ali Khamenei in U.S.-Israeli strikes.

Israel, which kept up its strikes in Lebanon even before the war despite a 2024 ceasefire, has since launched air raids across Lebanon and sent ground troops into border areas -- an offensive that has left 570 people dead according to the health ministry.

Iran's military on Wednesday said any ships belonging to the United States, Israel or their allies passing through the strategic Strait of Hormuz will be targeted.

"Any vessel whose oil cargo or the vessel itself belongs to the United States, the Zionist regime or their hostile allies will be considered legitimate targets," said the military's central operational command, Khatam Al-Anbiya, in a statement carried by state TV.

The war raging in much of the Middle East must be stopped before it engulfs the entire region at increasing cost to the global economy, Turkish President Recep Tayyip Erdogan said Wednesday.

Iran's new supreme leader Mojtaba Khamenei is injured but "safe and sound", the son of the president said Wednesday, offering the first official explanation for why the 56-year-old has not been seen since his appointment at the weekend.

"I heard news that Mr Mojtaba Khamenei had been injured. I have asked some friends who had connections," Yousef Pezeshkian, who is also a government adviser, wrote in a post on his Telegram channel.

Israeli strikes have killed 570 people in Lebanon since the Middle East war spread to the country on March 2, the health ministry said on Wednesday.

The ministry provided a demographic breakdown of those killed, reporting that 439 of them were men, 45 women, and 86 children.

Israel pressed its attacks across Lebanon on Wednesday, hitting an apartment building in central Beirut, in the second targeting of the heart of the capital since the Middle East war began.

Lebanon was drawn into the war last week when Hezbollah attacked Israel in response to the killing of Iranian supreme leader Ayatollah Ali Khamenei in U.S.-Israeli strikes.

An Israeli air strike killed ten people, including 4 children, and wounded 17 others in an east Lebanon town on Wednesday, the Lebanese health ministry said, as the war in Lebanon entered its 10th day.

The strike targeted a building inhabited by a Syrian family in Tamnin al-Tahta. In Ali al-Nahri, five people were wounded in a strike.

Fresh Israeli strikes hit Beirut's southern suburbs and south Lebanon on Tuesday after the Israeli army warned people to evacuate, with Lebanese authorities saying nearly 760,000 people had been registered as displaced.

A German court on Tuesday jailed a 35-year-old man for supplying Hezbollah with equipment for drones.
