The Jammu and Kashmir Police has sought around 22,500 additional paramilitary personnel for deployment along the entire route of the Amarnath pilgrimage, for which multi-tier security arrangements will be put in place, officials said on Sunday.

The pilgrimage to the shrine in south Kashmir Himalayas begins on June 28. Tracking of pilgrims' movement through satellites, installation of jammers, CCTV cameras and bulletproof bunkers, deployment of dog squads and quick reaction teams will be part of the security drill along pilgrimage routes.
