American forces have carried out additional strikes against multiple targets in Iran after Tehran's latest attack on a commercial ship near the Strait of Hormuz, the US' military Central Command (CENTCOM) confirmed.

CENTCOM said on Saturday its forces conducted the strikes June 27 "at the Commander in Chief's direction."

It said the strikes came after Iranian forces launched a one-way attack drone that hit the M/T Kiku at 4.30 am ET while the Panama-flagged tanker was transiting near the Strait of Hormuz with more than 2 million barrels of crude oil.

"CENTCOM forces launched strikes today in direct response to continued Iranian aggression against commercial shipping," it said.

US military aircraft targeted Iranian military surveillance infrastructure, communication systems, air defence sites, drone storage facilities and minelayer capabilities, it added.

The command said commercial vessel transits through the Strait of Hormuz continue, and that US forces "remain vigilant, lethal, and ready."

Explosions reported across southern Iran

Several explosions were heard early Sunday in the city of Sirik in southern Iran, Iranian state television reported.

The broadcaster, citing a military source, said projectiles hit a telecommunications tower in Tahrouyi village.

Iran's Fars News Agency separately reported that an explosion was heard in Misin village on Qeshm Island in southern Iran.

No immediate information was available about possible casualties.

The US' military Central Command (CENTCOM) announced Sunday additional strikes on multiple targets in Iran, saying American forces targeted Iranian military surveillance infrastructure, communication systems, air defence sites and drone-related facilities after accusing Tehran of continued actions against commercial shipping near the Strait of Hormuz.
