CENTCOM Says Blockade Will Begin Monday Morning at 1000ET

U.S. Central Command (CENTCOM) forces will begin implementing a blockade of all maritime traffic entering and exiting Iranian ports on April 13 at 10 a.m. ET, according to a statement on X.

CENTCOM provided some further clarification in regard who will be blocked, in accordance with President Trump's earlier proclamation.

Specifically, they are only (and impartially) blocking any vessel leaving or entering an Iranian port...

The blockade will 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.

But, vessels from non-Iranian ports are free to transit the Strait

CENTCOM forces will not impede freedom of navigation for vessels transiting the Strait of Hormuz to and from non-Iranian ports.

Now the fun begins.

Iran Says It Won't Allow Blockade Of Hormuz Strait, But Room For Diplomacy Remains

As the US failed to open the Strait of Hormuz, it is also "doomed to fail in a naval blockade," Iran's military adviser to the supreme leader, Mohsen Rezaee, said in a post on X.

Iran's armed forces "will not allow America to do so and have great untapped leverage to counter it," he adds.

"Iran is not a place to be surrounded by tweets and imaginary plans."

However, despite defiant statements from the U.S. and Iran, The Wall Street Journal reports that, according to regional officials familiar with the matter said, the door remains open for further diplomacy and a second round of talks could be held within days. Regional countries were also in consultation with the U.S. to secure an extension of the fragile two-week ceasefire period announced late Tuesday, they said. 

The Islamabad talks were the highest-level face-to-face meeting between American and Iranian leaders since 1979. The main sticking points, said the officials, were reopening the Strait of Hormuz without collecting fees, the fate of Iran's highly enriched uranium, and Iran's demand that about $27 billion in frozen revenues held abroad be released. Iranian officials have presented counterproposals to continue to enrich token amounts or curtail its stockpile of enriched uranium, but the two sides were unable to reach a compromise, the officials said.
