Iran closed the Strait of Hormuz on Saturday, reversing its brief reopening just one day earlier and adding fresh uncertainty to ongoing nuclear negotiations with the United States. The move came as both sides reported diplomatic progress despite fundamental disagreements over nuclear issues and control of the strategic waterway.
The closure affects one-fifth of global oil shipments and strands hundreds of vessels with approximately 20,000 seafarers awaiting passage through the Gulf. Tehran justified the action as a response to continued US blockade of Iranian ports, which it called a violation of the current ceasefire agreement.
We have had progress but there is still a big distance between us. There are some issues on which we insist ... They also have red lines. But these issues could be just one or two.

President Trump acknowledged the diplomatic engagement while condemning Iran's strait closure as blackmail. He defended the US maritime blockade of Iranian ports and threatened to resume military action if no long-term agreement emerges before the ceasefire expires Wednesday.
The eight-week conflict between the US-Israeli coalition and Iran has killed thousands and spread to Lebanon, where Israeli forces reported one soldier killed and nine wounded in recent fighting. Oil prices have surged due to the strait's effective closure since the war began February 28.
The Straits Times emphasizes the maritime and economic implications of the strait closure, highlighting the human cost with specific details about stranded seafarers. As a major shipping hub, Singapore's perspective focuses on the disruption to global trade routes and the practical consequences for international commerce rather than taking sides in the geopolitical dispute.
