US naval blockade against Iran begins raising stakes in Middle East

The United States has reimposed a comprehensive naval blockade on all Iranian ports, effectively dismantling the fragile diplomatic truce established last month to pause the conflict.

US Central Command (CENTCOM) confirmed the maritime blockade took effect at 2000 GMT on Tuesday on orders from President Donald Trump, targeting all merchant and energy traffic entering or exiting the country’s coastal waters.

The strategic intervention revives a severe economic clampdown that was previously enforced from mid-April until mid-June, which was only lifted after Washington and Tehran signed a temporary 14-point memorandum of understanding.

Collapse of June agreement

The resumption of the naval blockade follows the near-total collapse of the interim ceasefire, which world leaders hoped would provide a pathway toward a permanent settlement.

During the initial two-month blockade earlier this year, CENTCOM forces redirected more than 140 compliant vessels and disabled nine non-compliant ships.

Senior Iranian officials stated on Tuesday that the renewed deployment of American warships to block national ports effectively wrecks the active diplomatic framework, which had been mediated by Oman, Qatar and Pakistan to prevent an all-out regional war.
