Two Pakistani security sources say that negotiations between the United States and Iran are likely to take place before Friday. These talks are expected to happen in Islamabad. According to the sources, there are clear signs of preparation. Two large US military aircraft, known as C-17 Globemasters, have landed at Noor Khan Airbase in Rawalpindi. This usually shows that important officials or equipment have arrived. Security in the capital has also been increased. Roads from the airport to Islamabad’s Red Zone have been temporarily closed, which often happens during high-level visits. In addition, major hotels like Serena and Marriott in Islamabad are being cleared of guests, and no new bookings are allowed for now. This suggests that these places may be used for official meetings. Earlier, the first round of talks between the US and Iran was held at Serena Hotel on April 11. These new developments indicate that another round of important discussions may happen very soon.
