ISLAMABAD: The federal capital remained under heightened security on Wednesday as the Red Zone stayed sealed, with uncertainty surrounding the expected United States Iran talks keeping authorities on high alert and residents on edge.

While several routes across the city were gradually reopened, access to the High Security Zone remained restricted, with only essential personnel allowed entry. Security forces including army, Rangers and police maintained a strong presence, conducting patrols and manning checkpoints in and around sensitive locations.

Planned diplomatic activity faced last minute disruptions after the expected arrival of United States Vice President JD Vance was abruptly altered, while Iran’s delegation also delayed confirmation of participation. The uncertainty stalled full scale deployment plans across the city, though precautionary measures remained firmly in place.

The restrictions significantly impacted daily life as markets operated at low activity levels, educational institutions shifted to online classes and many government employees worked remotely. Traffic flow dropped sharply, and transport operations were partially suspended, although essential supply chains continued without major shortages.

Residents, particularly those living near the High Security Zone, reported difficulties due to road closures and longer travel routes, while ride hailing fares surged due to increased demand. Public reaction remained mixed, with some viewing the situation as a sign of Pakistan’s global relevance and others expressing frustration over prolonged disruptions.

Authorities also carried out extensive search and combing operations across multiple sectors, detaining several suspicious individuals for verification. Meanwhile, the Federal Constitutional Court suspended proceedings for the day, citing access challenges, as the capital continues to navigate the pressures of high stakes diplomacy and strict security enforcement.
