The Central government’s security managers will throw an unprecedented eight-layer protection ring around United States President Barack Obama during his three-day high-profile visit to India, beginning from February 25. 

US Secret Service personnel will form the two innermost circles to shield Obama, much like the way the Special Protection Group closely guards Prime Minister Narendra Modi, while the remaining arrangements are left to the paramilitary forces and the Delhi Police. 

Acceding to the US administration's request, the Centre has also decided to extend a “no-fly zone” from 300 m to 500 m, so restrictions in the sky go beyond Rajpath to Maurya Sheraton Hotel where Obama will stay.Only Indian Air Force aircraft has been allowed to carry out flypast on Republic Day, while no landing and take-off of civilian aircraft will take place that day for an hour and a half.

These issues were sorted out by top security managers in a Monday-evening meeting.  Delhi will see a complete lockdown, given the threat perception that Pakistan-based banned terror outfit Lashkar-e-Toiba might carry out an attack during Obama’s visit.
