"Those behind the attack are responsible for the consequences of this dangerous adventure, including the dangerous environmental pollution caused," Foreign Ministry spokesman Abbas Mousavi told state TV.

"None of the crew members were injured in the explosion and the situation is under control," said Iran's Nour news agency, which is close to the Iranian Revolutionary Guard Corps.

but a US official said they originated from southwestern Iran.
Riyadh also blamed Tehran, but Iran, which supports the Houthis in Yemen's war, has denied any involvement.
