Iran’s Revolutionary Guard said Friday that a liquefied petroleum gas tanker struck a mine, causing an explosion, while trying to sail through the Strait of Hormuz, according to state-run IRNA news agency.

The Guard said the vessel ignored repeated warnings while transiting the eastern part of the strait. The claim could not be independently verified, and there was no immediate report of the incident from the United Kingdom Maritime Trade Operations, a British military agency that monitors incidents at sea.
