A report from a flight tracking website has revealed that the arrival of American military aircraft in Islamabad has begun.
According to the report, large US Air Force cargo planes, Boeing C-17 Globemaster III with equipment, have landed at Nur Khan Air Base ahead of a possible visit by top US officials to Islamabad.
According to flight data, three planes arrived at different times on April 19, the first at 8:30 a.m., the second at 11:03 a.m., and the third at 2:40 p.m., while another plane is also reported to be en route.
More US aircraft were seen refueling at Ramstein Air Base and Moron Air Base, suggesting a wider logistics operation.
The planes reportedly brought security, communications systems and other support equipment, which are usually deployed ahead of high-level US visits, although officials have not yet officially confirmed any visits.
Earlier, reports had emerged about an advance US delegation arriving in Islamabad.
According to sources, advance teams of foreign delegations are arriving in the country ahead of the upcoming important negotiations.
The Red Zone in the federal capital has been closed to traffic to ensure security during the visit of foreign delegations.
