The US military announced that it had disabled a St. Kitts-flagged cargo ship in the Gulf of Oman after the vessel allegedly attempted to breach a naval blockade.

US Central Command said the ship ignored warnings and tried to depart after visiting an Iranian port.

Meanwhile, Iranian media reported explosions in southern Iran on Saturday. Britain’s maritime trade agency also reported an incident involving a bulk carrier and military forces.

Iran’s Revolutionary Guard dismissed a new US plan to increase economic pressure on Tehran as “wordplay.”

The developments followed reports of an attack on an Aramco building in Saudi Arabia and continued strikes in Yemen, raising concerns about maritime security and energy supplies.
