WASHINGTON, United States, June 6, 2026 (BSS/AFP) - The United States military said it attacked radar sites on Iran's southern coast Friday in the latest flare-up to threaten the ceasefire in the Mideast war.

US Central Command said in a statement that its forces shot down four Iranian one-way attack drones launched toward the Strait of Hormuz, then attacked Iranian coastal surveillance radar sites in the city of Goruk and on Qeshm Island.

"The attack drones posed an immediate threat to regional maritime traffic," while the strikes on radar installations "defend against further attacks," the statement said.

Iranian state broadcaster IRIB reported on Saturday that "several explosions were heard" in Sirik in southern Iran at around 2:30 am (2300 GMT Friday).

"No official source has commented on the origin of the sound or its details," the broadcaster said on Telegram.

Kuwait's military said early Saturday it was responding to "hostile" missile and drone attacks, days after a strike on the country's international airport killed one and wounded dozens.

"Kuwaiti air defenses are currently responding to hostile missile and drone attacks," the military said on X, without specifying their origin.

A ceasefire has been in place between the United States and Iran since April 8, but subsequent talks to try to put a more permanent end to the conflict have so far been unsuccessful.

US President Donald Trump is under pressure to find a way out of the war, which has delivered a shock to markets and proven unpopular at home as midterm elections loom.

Trump acknowledged in an interview with NBC News late Friday that Iran still has war-fighting capacity.

"They have some missiles, they have some drones. I would say, percentage wise, maybe 21, 22 percent of their missiles," Trump said.

Iran's military said Friday it had fired "warning missiles" at two US destroyers in the Gulf of Oman -- a claim promptly denied by the US military.

Two days earlier, Kuwait said it had intercepted 30 ballistic missiles fired as part of "heinous Iranian aggression."
