Here are the latest developments:
The opposition says the government must explain whether intelligence alerts were not taken seriously or acted upon. In Delhi, intelligence agencies warned 72 hours ago of a possible terror strike in cities, including Hyderabad and Bangalore. (Intelligence alert mentioned Hyderabad)
Home Minister Sushil Kumar Shinde, who visited Hyderabad today, said there was intelligence about attacks, but that it was general. (Watch)
But Leader of the Opposition in Lok Sabha, Sushma Swaraj, pointed out in Parliament this morning that in October, the Delhi Police said that alleged Indian Mujahideen terrorists had disclosed that they had surveyed Dilsukhnagar as the location for a possible terror strike. (Hyderabad blasts despite intelligence reports: Sushma Swaraj)
This morning, police with cameras and gloves searched the debris in Dilsukhnagar. Officials from the National Investigation Agency and commandos of the National Security Guard arrived from New Delhi to help with the investigation. (See pics of blasts)
Crucial forensic evidence may have been destroyed by crowds swarming the area last night, who ignored police orders to leave the area for several hours.
Among the 16 people who were killed were three young students who were at the market to buy textbooks. (Among injured, man who survived Mecca Masjid blast)
Police say Improvised Explosive Devices or IEDs were used in the blasts. Traces of RDX have been found. Timers were used to trigger the explosions.
Andhra Pradesh Chief Minister Kiran Kumar Reddy today denied reports that wires of a security camera near the location of the blasts had been snapped four days ago. Traffic police sources had said they were aware of the CCTV camera not working but did not re-connect it.
The bombs, placed on bicycles near a small restaurant in Dilsukhnagar, went off just after 7 pm yesterday, within five minutes of each other. The Hyderabad police chief, on way to the Sai Baba temple, had passed by about 15 minutes ago.
The test match between India and Australia, scheduled to start in Hyderabad on March 2, has not been re-scheduled.(Read)
