In a statement posted on X, US Central Command (Centcom) said the operation ended at 21:30 ET (02:30 BST) after several hours.

"U.S. forces employed fighter aircraft, aerial drones, and warships in addition to other assets," the statement said.

Iran said it retaliated by launching attacks against US allies across the Gulf. Kuwait's military said its air defences had been "confronting hostile missile and drone attacks" following what it described as "Iranian aggression."

Jordan's military said it intercepted 10 Iranian missiles that entered its airspace overnight. Authorities reported no damage.

Iran's armed forces also claimed they had targeted multiple US military facilities in Kuwait, Bahrain, Jordan and, for the first time, Syria. Washington denied the claims.

Earlier, Kuwaiti officials said Iranian drone attacks injured several soldiers and damaged a power plant and water desalination stations.

Sources told CBS News, the BBC's US partner, that several American service members were injured during Iranian attacks on two US bases in Jordan over the past week.

Iranian state media reported explosions in the central city of Yazd, on Qeshm Island and at the port city of Bandar Abbas near the Strait of Hormuz.

The state-run Fars news agency also reported that two oil tankers "exploded and caught fire while passing through a mined route south of the Strait of Hormuz." Centcom rejected the report, posting on X: "Like most IRGC claims, this is false."

The continuing exchange of attacks has disrupted shipping through the Strait of Hormuz, a strategic waterway that normally carries about one-fifth of the world's oil and liquefied natural gas supplies, raising concerns over global energy markets.

Washington also rejected Tehran's accusations that US forces had struck civilian infrastructure, including bridges, a railway station and an airport.

A White House spokesperson said the US had "carried out strikes exclusively on military targets, including military logistics infrastructure".

However, authorities in Iran's Hormozgan province said seven people were killed in the attacks.

BBC Verify and BBC Persian confirmed damage to Gariveh Bridge, where overnight footage showed a large fire. Images taken later revealed part of the bridge had collapsed, leaving rubble scattered across the damaged roadway.
