The US Central Command announced enforcement of a naval blockade on all maritime traffic to and from Iranian ports beginning April 13 at 10 am ET. President Trump announced the blockade after failed negotiations with Iran over nuclear ambitions and the Strait of Hormuz. Iran's Foreign Minister claimed the countries were close to agreement before the blockade announcement. CENTCOM stated the blockade would be enforced impartially against all vessels entering Iranian ports while allowing transit to non-Iranian destinations.
