The US military says it has launched "self-defense" strikes on Iran and shot down ballistic missiles and drones fired at ships and Gulf countries.
The strikes on Qeshm Island, in the Strait of Hormuz, were "in response to attempted attacks by Iran across the Middle East", US Central Command (Centcom) said.
Iran said it had attacked US bases and helicopters in a "regional country" using missiles and drones in retaliation. Centcom said Tehran had fired two missiles at Kuwait and three at Bahrain, all of which broke apart or were intercepted.
Centcom added the strike on Qeshm Island had targeted an Iranian military ground control station, and that the US military also shot down three attack drones that had been launched by Iran toward "civilian mariners that were rightfully transiting regional waters".
Centcom also said that Iran had launched "several" ballistic missiles towards countries in the region. "Two Iranian missiles fired at Kuwait fell short or broke apart enroute, and three missiles launched at Bahrain were immediately intercepted by US and Bahrain air defense forces."
Iran has repeatedly attacked targets in Bahrain and Kuwait, where US military bases are located.
Earlier, Centcom said it has struck and disabled an unladen oil tanker that was sailing towards Iran, as part of Washington's naval blockade on the Strait of Hormuz, which began on 13 April.
A US aircraft fired a Hellfire missile into the engine room of the Botswana-flagged M/T vessel, after its crew "ignored repeated warnings", it said.
Centcom also released a footage purportedly showing the moment the tanker was hit on Tuesday.
