Kuwait said Tuesday that four people arrested earlier this month as they attempted to enter the country by sea have confessed to belonging to Iran's Revolutionary Guards.
The four men - two navy colonels, a captain, and a lieutenant commander - admitted they had been tasked by the IRGC with "infiltrating" Bubiyan Island, Kuwait's interior ministry said in a statement published by state news agency Kuna.
The island is Kuwait's largest and is located near the Iranian coast. The group attempted to enter on 1 May "aboard a fishing boat specially chartered to carry out hostile actions against Kuwait", the ministry said.
A Kuwaiti serviceman was wounded during an exchange of fire with Kuwaiti forces on the island, and two of the Revolutionary Guard members managed to escape, it added.
On 3 May, the defence ministry said it arrested four people attempting to enter Kuwait by sea.
Since the US-Israeli war on Iran began in late February, Kuwaiti authorities have sought to crack down on individuals and groups with alleged links to Iran.
And in mid-April, 24 people were arrested in the country for financing "terrorist" entities, according to the interior ministry, while a security source said five former lawmakers were among those arrested.
