"A container ship attempting to cross the Strait of Hormuz using an unauthorised and dangerous shipping lane struck a mine that exploded," said the navy of the Revolutionary Guards, the ideological arm of Iran's military.

Images released by the Guards show a plume of black smoke rising from a ship, while dozens of containers that have fallen into the sea float on the water.
