The first mock convoy movement drill along the highway was conducted successfully on Monday. Authorities have also retained last year's ban on helicopter services for pilgrims from both the Pahalgam and Baltal routes amid heightened security concerns. The airspace over both routes has been declared a no-flying zone, and security personnel have been equipped with anti-drone systems to counter aerial threats. Additionally, seven National Disaster Response Force (NDRF) teams have been positioned for rescue operations, while the India Meteorological Department (IMD) has strengthened weather monitoring along the pilgrimage route with automated weather stations and additional nodal officers. Officials said CAPF personnel deployed along the convoy route, base camps and trekking track have been issued anti-drone jammers. Two National Security Guard (NSG) units have also been stationed along the route -- one tasked with neutralising unidentified aerial objects and another functioning as quick reaction teams for emergency response.
