CENTCOM Announces Blockade Enforcement Details
The U.S. Central Command stated in a post on X that at the Commander in Chief's direction, U.S. forces will resume blockading maritime traffic entering and exiting Iranian ports beginning July 14 at 4 p.m. ET. CENTCOM forces will enforce the blockade against vessels transiting to or from Iranian ports and coastal areas, while the U.S. military continues to support traffic flow through regional waters for all vessels not violating the blockade.
CENTCOM said the renewed operation follows the initial implementation between April 13 and June 18, during which forces redirected more than 140 compliant vessels, disabled nine non-compliant ships, and allowed over 50 commercial vessels supporting humanitarian aid to pass through the blockade. Mariners operating in the Gulf of Oman and approaches to the Strait of Hormuz were advised to monitor Notice to Mariners broadcasts and contact U.S. naval forces on bridge-to-bridge channel 16.
Trump Declares Strait of Hormuz Access Policy
Trump said in a post on Truth Social that the Iranian blockade had been reinstated following hostilities between the U.S. and Iran that began last week. "The Hormuz Strait is open, and will remain open, with or without Iran. We are reinstating the Iranian blockade, so named because it is only stopping Iran's ships or customers from entering or leaving," Trump stated. He added that all countries except Iran will have fair and open access to the Strait of Hormuz.
