Iran’s Islamic Revolutionary Guard Corps (IRGC) says it has targeted an American air base in the region, after fresh US strikes on southern Iran.

The IRGC did not say where the base was, but Kuwait, which hosts a US base, said it had intercepted “hostile missile and drone threats”, without specifying where they were coming from. Earlier the US military said it had shot down Iranian drones over the Strait of Hormuz and struck a military site in Bandar Abbas, a strategic port city.

The renewed hostilities threaten a fragile ceasefire between the US and Iran, reports the BBC. It is the second time in three days that the US has attacked targets in Iran – saying that the strikes were conducted in self-defence.

The site in Bandar Abbas was struck as it was about to launch a fifth drone, US Central Command (Centcom) said. Iranian media reported that explosions were heard to the east of the city.

Meanwhile, details about the strikes emerged after Trump, at a Cabinet meeting earlier Wednesday, expressed confidence that his administration was making headway on settling the war, even though the talks still remain very much in flux, reports The Associated Press. Iranian foreign ministry spokesman Esmail Baqai meanwhile condemned the US strikes and said they constituted a violation of the ceasefire.
