The oil-rich Gulf nation, a US ally, has been on the receiving end of Iranian attacks since the US and Israel attacked Iran and killed its senior leadership in late February.

“Any sounds of explosions heard are the result of air defence systems intercepting these hostile attacks,” the military said on X, without specifying their origin.

Kuwait’s state-run news agency KUNA reported that sirens were heard for the second time that night.

On Monday, Kuwait said it downed a volley of missiles and drones, and later its foreign ministry held Iran “fully responsible for these heinous attacks”.

The US military’s Central Command had said its forces “successfully intercepted two Iranian ballistic missiles targeting American forces based in Kuwait”.

“These missiles were immediately defeated and no American personnel were harmed,” it said in a post on X.
