Islamabad (Pakistan), 12 April (LaPresse) – Talks between the United States and Iran, hosted in Islamabad, Pakistan, have ended without an agreement after more than 21 hours of negotiations. According to Iranian state television, the failure was due to ‘unreasonable demands’ made by Washington. US Vice-President JD Vance confirmed the deadlock, highlighting the absence of a definitive commitment from Tehran to abandon its nuclear programme. Vance then announced his return to the United States after presenting what he described as ‘the best possible final offer’. The issue surrounding the Strait of Hormuz also remains unresolved. Pakistani Foreign Minister Ishaq Dar urged both sides to respect the ceasefire. Islamabad reiterated its willingness to continue in its mediating role to facilitate dialogue.
