Talks collapse amid rising tensions
The Strait of Hormuz blockade announced by Donald Trump has heightened global tensions after US-Iran talks in Pakistan collapsed.
The US President confirmed that American forces would begin a blockade of Iranian ports starting Monday afternoon, blaming Tehran’s refusal to abandon its nuclear ambitions for the breakdown in negotiations.
The talks, held in Islamabad and mediated by Pakistan, had raised hopes for a longer-term agreement following a fragile two-week ceasefire. However, their collapse has renewed fears of escalation in a conflict that has already killed thousands since late February.
US military outlines blockade plan
US Central Command said the blockade would apply to vessels entering or leaving Iranian ports along the Arabian Gulf and Gulf of Oman.
However, US forces would not prevent ships transiting the Strait of Hormuz if they are travelling to or from non-Iranian ports.
Trump initially suggested a broader operation, stating that all ships attempting to pass through the strait could be blocked, before confirming a more limited approach.
Iran reacts with defiance
Iranian officials strongly rejected the move. Parliament Speaker Mohammad Bagher Ghalibaf said Tehran would “not bow to any threats,” while naval commander Shahram Irani dismissed the blockade as “ridiculous”.
Foreign Minister Abbas Araghchi blamed the failure of talks on what he described as “maximalism, shifting goalposts and blockade”, claiming the sides were close to reaching an agreement.
Iran’s Revolutionary Guards had earlier warned that they control traffic through the strategic waterway and could respond forcefully to any challenge.
Oil prices surge above $100
The announcement of the Strait of Hormuz blockade sent oil markets sharply higher, with both Brent and WTI crude rising by around 8% to exceed $100 per barrel.
The strait is a critical global energy route, and any disruption has immediate consequences for international markets and supply chains.
Ceasefire at risk
Pakistan, which hosted the negotiations, said it would continue efforts to facilitate dialogue and urged both sides to respect the ceasefire agreed last week.
Experts warn that a maritime blockade could effectively signal a return to active conflict, putting the already fragile truce at risk.
Meanwhile, tensions remain high across the wider region, including Lebanon, where exchanges involving Hezbollah and Israeli forces continue despite the ceasefire framework.
Uncertain path ahead
Trump expressed indifference over whether talks resume, stating that the US would proceed regardless of Iran’s participation.
With military movements intensifying and diplomatic efforts faltering, the situation remains volatile, with global markets and regional stability closely tied to developments around the Strait of Hormuz blockade.
