Hyderbad: Three days after twin blasts claimed 16 lives and injured 117 in Hyderabad, Prime Minister Manmohan Singh on Sunday visited the injured in the hospital and urged people to 'maintain calm in the hour of grief'. Even as Union Home Minister Sushil Kumar Shinde said evidence recovered from the blast sites were under examination, the National Investigation Agency questioned 12 men - believed to be members of the Lashkar-e-Toiba - arrested in Bangalore.
