Footage on Sunday (April 12) showed vessels in the Strait of Hormuz off the coast of Oman.

U.S. President Donald Trump said on Sunday the U.S. Navy would start blockading the Strait of Hormuz, raising the stakes after marathon talks with Iran failed to reach a deal to end the war, jeopardizing a fragile two-week ceasefire.

The U.S. Central Command said U.S. forces would begin implementing the blockade of all maritime traffic entering and exiting Iranian ports at 10 a.m. ET (1400 GMT) on Monday (April 13).

It would be "enforced impartially against vessels of all nations entering or departing Iranian ports and coastal areas, including all Iranian ports on the Arabian Gulf and Gulf of Oman," a CENTCOM statement on X said.

U.S. forces would not impede freedom of navigation for vessels transiting the Strait of Hormuz to and from non-Iranian ports, and additional information would be provided to commercial mariners through a formal notice prior to the start of the blockade, it said.
