Iran's foreign ministry spokesman, Esmaeil Baqaei, announced that the country has no plans to attend further negotiations with the United States, following the US's seizure of an Iranian cargo ship. This incident has heightened tensions amid accusations from both sides regarding violations of a ceasefire agreement. President Donald Trump indicated that US negotiators would arrive in Islamabad, Pakistan, to discuss ending the conflict, which has been ongoing since February 28. The situation remains precarious, with Iran threatening retaliation for the cargo ship seizure and the US asserting that Iran has breached the ceasefire in the Strait of Hormuz. Oil prices spiked as fears of resumed hostilities grew, particularly after Iran temporarily closed the Strait of Hormuz. Security has been tightened in Islamabad in anticipation of the US delegation's arrival, which will be led by Vice President JD Vance. The negotiations are complicated by issues such as Iran's stockpile of enriched uranium, which Iran insists will not be transferred to the US.
