In a post on X on Wednesday, Araghchi described the interception and arrests as illegal, accusing Kuwait of attempting to sow discord in a region already strained by US-Israeli actions against Iran.

Authorities in Kuwait said that four people linked to the IRGC were arrested on May 3 after attempting to infiltrate the island by fishing boat to carry out “hostile acts”.

Two others escaped, and one Kuwaiti security officer was wounded, the Kuna news agency said.

The suspects reportedly confessed to being affiliated with the IRGC.

The Iranian minister said the incident occurred near an island in the Persian Gulf where US forces are stationed to conduct operations against Iran.

“In a clear attempt to sow discord, Kuwait has unlawfully attacked an Iranian boat and detained four of our citizens in the Persian Gulf. This illegal act took place near an island used by the US to attack Iran,” Araghchi wrote.

Kuwaiti territory has previously served as a staging ground for US military operations against Iran, particularly during the February-April conflict that ended with a ceasefire.

Iran has retaliated against US forces in Kuwait during the conflict, reportedly causing significant losses, including fatalities.

Araghchi further urged Kuwait to remove US forces from its territory to avoid future Iranian reprisals.

He emphasised that Iran reserves the right to respond to the latest detention if the four Iranian nationals are not released promptly.
