President Donald Trump has directed the United States Navy to commence a blockade of the Strait of Hormuz following renewed tensions with Iran over its nuclear programme.
Trump announced the directive on Sunday via his Truth Social platform, stating that the move became necessary after Tehran declined to abandon its nuclear ambitions during recent diplomatic engagements held in Islamabad.
He noted that although negotiations had recorded progress on several fronts, Iran’s refusal to compromise on its nuclear programme prompted decisive action.
“Effective immediately, the United States Navy will begin the process of blockading all ships attempting to enter or exit the Strait of Hormuz,” Trump declared, warning that any hostile action against US or commercial vessels would be met with force.
The development follows high-level talks involving US Vice President JD Vance and an Iranian delegation led by parliamentary speaker Mohammad Bagher Ghalibaf. The meeting marked one of the most significant engagements between both countries since the 1979 Iranian Revolution but ended without a breakthrough.
Iran’s team also included Foreign Minister Abbas Araghchi, while Washington described its proposal as a final offer pending Tehran’s response.
Tensions have escalated in recent weeks, with the US accusing Iran of obstructing maritime activities in the Strait of Hormuz a critical global oil transit route through which a significant portion of the world’s crude supply passes.
Trump further alleged that Iran had threatened the safety of vessels in the area, raising concerns among international shipping operators.
Meanwhile, the US military confirmed that two naval vessels had earlier passed through the strait as part of ongoing mine-clearing operations, signalling an increased security presence in the region.
The situation continues to draw global attention amid fears of disruptions to oil supply and heightened geopolitical instability.
