Hyderabad:
A team of top officials from the National Investigation Agency or NIA and the Intelligence Bureau has reached Hyderabad, where two blasts have killed at least 14 people and injured 119 yesterday evening.
A post-blast investigation team of the National Security Guard, the country's premier counter-terror force, is accompanying the team, Union Home Secretary RK Singh said. The NSG operates the National Bomb Data Centre.
The local unit of the NIA was already at the site of the blasts in Hyderabad, Mr Singh said.
PTI quoted sources to say that experts from the Chennai hub of the "black cat" commando force have also been rushed to the Andhra Pradesh capital.
Sources in the Home Ministry said the explosions in the city's Dilsukhngar were a terror strike by "a well-trained" group which timed the explosions to cause the maximum damage. Home Minister Sushil Kumar Shinde said the government had some intelligence inputs about a possible terror attack, but it had no specific details.
The Prime Minister has directed the central agencies to extend all possible help to the Andhra Pradesh state authorities in relief operations.
Delhi, Mumbai and other major cities in the country have been put on high alert after the Hyderabad blasts.
