“We have taken all the steps according to international laws,” Herath said.
Sri Lanka also provided safe haven to a second Iranian warship, the IRIS Bushehr, and evacuated its 219 crew a day after the Dena was torpedoed.
The ship was taken to Trincomalee on Sri Lanka’s northeast coast after reporting engine problems.
India, meanwhile, said on Saturday (local time) it had allowed a third Iranian warship, the IRIS Lavan, to dock in one of its ports on “humane” grounds after it too reported operational problems.
The three ships were part of a multi-national fleet review held by India before the war in the Middle East started.
“I think it was the humane thing to do and I think we were guided by that principle,” Indian Foreign Minister Subrahmanyam Jaishankar said.
The Lavan docked in the southwest Indian port of Kochi on Wednesday (local time).
“A lot of the people on board were young cadets. They have disembarked and are in a nearby facility,” Jaishankar said.
Sri Lanka President Anura Kumara Dissanayake said this week that Colombo would follow the Hague Convention, which requires a neutral state to hold combatants of a warring state until hostilities end.
A senior administration official said Colombo was in talks with the International Committee of the Red Cross to deal with the survivors of the torpedoed ship.
International humanitarian law applied to the survivors from the Dena, an official said, and the wounded could be repatriated at their request.
Iranian diplomats in Colombo said they have asked for the remains of 84 sailors killed in the US attack to be taken back to Iran.
