The United States is planning to begin a naval blockade of ships entering or leaving the Strait of Hormuz after U.S.-Iran ceasefire talks in Pakistan ended without an agreement. The move comes as President Donald Trump criticizes Iran for its nuclear ambitions and threatens to strike civilian infrastructure if the war continues. The blockade will involve all Iranian ports and will be enforced "enforced impartially" against all nations. However, CENTCOM will allow ships traveling between non-Iranian ports to transit the strait. This move is seen as a step down from earlier threats to block the entire strait and allows traffic to flow in the crucial waterway as long as it avoids Iranian ports. The announcement could further disrupt global energy markets. No word on what happens after the ceasefire ends on April 22.
