Mumbai, June 30 After the Mumbai terror attacks, the National Security Guard (NSG) hub at Mumbai will become operational today.

The NSG hubs at Chennai, Hyderabad and Kolkata will become operational on July 1.

Union Home Minister P Chidambaram and dignitaries from the State Governments will be present during the operationalisation ceremonies.

The Government has also sanctioned two NSG regional centres to be established at Kolkata and Hyderabad.

The existing hubs at Kolkata and Hyderabad will subsequently be merged with the regional centres.

The hubs have been established at Marol (23 acres) in Mumbai, Nedunkundram (85 acres) in Chennai, Trimulghery (22 acres) in Hyderabad and Badu (20 acres) in Kolkata.

Pre-fabricated and permanent structures are being constructed to station NSG commandos at these locations.

The National Buildings Construction Corporation Ltd (NBCC) has been assigned the construction work.

The State Governments including civil and police administration, Airport Authority of India and Army have extended full assistance in the establishment and operationalisation of the hubs within the scheduled time frame.

With the establishing of the hubs, the response time of NSG for countering any terrorist action would be reduced very significantly. (ANI)
