The United States has officially launched a naval blockade targeting all vessels entering or leaving Iranian ports, significantly escalating tensions in the region following the collapse of weekend peace talks in Pakistan.

The blockade came into effect at around 8pm on Monday (Dhaka time), with US forces beginning enforcement operations across maritime routes linked to Iran.

According to US military statements, the measure applies to all ships heading to Iranian ports as well as vessels suspected of paying transit “tolls” to Iran for passage through the strategically vital Strait of Hormuz.

However, US authorities said humanitarian shipments, including food and medical supplies, would still be permitted under strict inspection protocols to ensure compliance.

US President Donald Trump issued a strong warning following the launch of the blockade, stating that Iranian “fast attack ships” would be targeted if they approach the restricted zones. He added that although such vessels had previously been tolerated due to their limited threat level, any future movements near the blockade area would be met with force.

In response, Iran’s Islamic Revolutionary Guard Corps (IRGC) adopted a defiant stance, warning that military vessels from “any nation” approaching the Strait of Hormuz would face severe consequences. The IRGC reiterated that the waterway remains under Iran’s strategic watch.

The blockade follows the breakdown of negotiations aimed at easing hostilities, raising concerns about further escalation in the already volatile Middle East region.

Analysts warn that the move could disrupt global shipping routes and energy supplies, particularly as the Strait of Hormuz is a critical corridor for international oil and gas transport.
