New Delhi: Posters carrying photographs of 19 wanted terrorists linked to groups such as Indian Mujahideen, Al-Qaeda and Khalistani terror networks have been put up at multiple locations across the national capital as part of heightened security measures ahead of Independence Day, police said. The exercise is part of the annual security drill conducted ahead of August 15 and is aimed at increasing public awareness and seeking assistance from people in identifying and tracking people considered a threat to the national capital, officers said. The Red Fort, where the main Independence Day celebrations will be held, has been placed under a multi-layered security cover. Nearly 1,000 CCTV cameras, including facial recognition system-enabled cameras, have been installed at the Red Fort and its adjoining areas. Security arrangements have also been strengthened in view of intelligence inputs, with police maintaining a close watch on suspicious activities and movements in and around the national capital.
