US Vice President JD Vance's planned visit to Pakistan has been put on hold as Iran has not responded to the US's negotiating position ahead of important discussions. Reports from the New York Times indicate that while the talks are not canceled, the diplomatic process is effectively paused. Vance was set to depart for Islamabad on Tuesday morning, but the lack of commitment from Iran has raised concerns about the future of these negotiations. With the ceasefire, announced on April 7, nearing its expiration, urgency for talks increases. Statements from US President Donald Trump and Iranian officials highlight ongoing tensions, with both sides issuing threats. The ceasefire is reportedly set to expire at 3:30 am Tehran time on Wednesday, although conflicting reports suggest different end times. The situation remains fluid, and Vance's visit could be rescheduled if Iran provides an acceptable response.
