India started deploying troops along Rajasthan border. Security in and around Indian defence airstrips has been tightened. Indian Air Force(IAF) sources said security around places of strategic importance has been stepped up. They said more radars and QRTs have been deployed along the India-Pakistan border. IAF had initiated these measures to strengthen its air defence to face any eventuality at a short notice. Additional hangars and runways have been prepared and all the radars have been put on high alert. Sources said tight radar surveillance is being maintained to keep a watch on any suspected movements along the border. Indian forces were on regular firing exercises at locations like Lathi Firing Range in Jaisalmer, Mahsan in Bikaner, Suratgarh and Ganganagar.
