Air strikes between the US and Iran resumed over the weekend, with both sides claiming hits on military targets near the Strait of Hormuz.
US Central Command said it conducted "self-defense strikes" on Iranian radar and drone command sites in Goruk and Qeshm Island. Iran's Islamic Revolutionary Guard Corps retaliated by targeting a US air base used to launch the strikes, though it did not specify the location.
The US said its strikes were triggered by the shootdown of an American MQ-1 drone over international waters. No US personnel were injured.
Iran warned its response would be "completely different" if US aggression continues, according to remarks reported by Fars news agency.
Kuwait's military confirmed it was intercepting hostile missile and drone attacks. Tehran previously struck a Kuwaiti air base in response to US operations to clear mines from shipping lanes.
A ceasefire began on April 8, but no permanent deal has been reached. The latest proposal included a 60-day truce, reopening the Strait of Hormuz, and new talks on Iran's nuclear program. The waterway typically handles about one-fifth of global oil and LNG shipments, and the blockade continues to pressure fuel prices worldwide.
