The US military has begun enforcing a full blockade on all maritime traffic entering and exiting Iranian ports, marking a major escalation.

According to a breaking report from Al Jazeera, the US military has begun enforcing a blockade on all maritime traffic entering and exiting Iranian ports, marking a major escalation after the set deadline.

The move comes a day after the collapse of the latest round of ceasefire negotiations in Pakistan. The US had demanded verifiable limits on Iran’s nuclear programme and full, unrestricted access through the Strait of Hormuz. With those conditions unmet, Washington has now moved to increase economic pressure on Tehran.

Iran has already condemned the blockade as “an act of piracy” and warned of retaliation. Shipping companies and energy markets are on high alert as the situation develops rapidly.

This is the most direct naval enforcement action taken by the US since the two-week ceasefire was announced earlier this month.
