U.S. pressing Sri Lanka not to repatriate Iranian crew and survivors from sunken ship, memo says

The United States is pressing Sri Lanka’s government not to repatriate the survivors from the Iranian warship ‌it sank this week, as well as the crew of a second Iranian ship that is in Sri Lankan custody, according to an internal ⁠State Department cable seen by Reuters on Friday (March 6, 2026).

A U.S. submarine sank the IRIS Dena warship in the Indian Ocean about 19 nautical miles off Sri Lanka’s southern port city of Galle on Wednesday, killing ‌dozens of sailors and dramatically widening Washington’s pursuit of the Iranian navy.

On Thursday, Sri Lanka began offloading 208 crew members from a second Iranian ship, ‌the naval auxiliary vessel IRIS Booshehr, which had found itself stranded in Sri Lanka’s exclusive ‌economic ⁠zone but outside its maritime boundary.

President Anura Kumara Dissanayake said his ⁠island nation had a “humanitarian responsibility” to take in the crew.

The torpedoing of the Dena - which U.S. Defense Secretary Pete Hegseth described as “quiet death” - was the first such action by the United States since World War Two and a clear sign of the Iran conflict’s ‌widening geographic scope.

The internal State Department cable, which was dated March 6 and has not been previously reported, said Jayne Howell, the charge d’affaires at the U.S. embassy in Colombo, had emphasized to Sri Lanka’s government that neither the Booshehr crew nor ‌the 32 Dena survivors should be repatriated to Iran.

It said “Sri Lankan authorities should minimize Iranian attempts to use the detainees for propaganda.”

The State Department did not immediately respond to a request for comment. Representatives for Mr. Dissanayake’s office and Sri ⁠Lanka’s Foreign Ministry were not immediately available for comment.

The cable said Mr. Howell also told the Israeli ambassador to India and Sri Lanka that there was no plan to repatriate the crew ‌to Iran. The envoy asked Howell whether there was any engagement with the crew to encourage “defection”, the cable said.

A representative for the Israeli Embassy in New Delhi did not immediately respond to a request for comment.

On Wednesday, Sri Lanka’s Deputy Minister for Health and Mass Media, Hansaka Wijemuni, told Reuters that Tehran had asked Colombo for help repatriating the bodies of those killed aboard the Dena, but a timeframe to do so has not yet ‌been determined.

The Dena had taken part in naval exercises organised by India in the Bay of Bengal last month and was returning to Iran when it was struck by a U.S. torpedo.

A U.S. official, speaking on condition of anonymity, told Reuters the Dena ⁠was armed when it was hit and the United States did not provide a warning ⁠before carrying out the strike.

The State Department cable said the second vessel, the Booshehr, will remain in Sri Lankan custody for the duration of the conflict.

Sri Lankan ‌authorities said on Friday that they were escorting the Booshehr to a harbour on the eastern coast and moving most of its crew to a navy camp near Colombo.
