Iran's Islamic Revolutionary Guard Corps (IRGC) has seized two foreign commercial vessels in the Strait of Hormuz, hours after US President Donald Trump extended a ceasefire, reports Al Jazeera.

Iranian state media said the ships violated maritime regulations and entered the waterway without coordination. The move followed an incident in which an IRGC gunboat fired on a Liberian-flagged container vessel near Oman, causing heavy damage to its bridge but no casualties.

The IRGC said the seizures were in response to the US capture of an Iranian commercial ship in the Sea of Oman, accusing Washington of "armed piracy" after allegedly disabling its navigation systems. Iranian officials have also discussed imposing charges and transit fees for vessels using Hormuz.

The Strait of Hormuz handles about one-fifth of global oil supply and remains a critical chokepoint. Analysts said Tehran is seeking to assert authority over maritime traffic as leverage in negotiations, while sending mixed signals over the ceasefire.

US President Donald Trump said he would delay a planned military strike on Iran after requests from Pakistan's leadership, but confirmed the US naval blockade of Iranian ports would remain. He said American forces were ordered to stay "ready and able".

Observers noted mistrust between Tehran and Washington, with Iranian officials rejecting imposed terms and warning of further confrontation. Analysts said Iran views control of Hormuz as central to its regional strategy, framing its position around "security for all versus security for none".
