Seven people were killed and 27 were injured after a huge pile of confiscated explosives stored at a police station went off in Jammu and Kashmir's Srinagar on Friday night.
The casualties may rise as five of the injured are in a critical condition, sources told media.
Most of those killed are policemen and forensic team officials, who were examining the explosives.
Two officials from the Srinagar administration including a naib tehsildar also died in the explosion.
The injured have been rushed to the Indian Army's 92 Base Hospital and Sher-i-Kashmir Institute of Medical Sciences (SKIMS). Senior police officials have reached Nowgam, and the area has been cordoned off.
It was the Nowgam police station which cracked the case of terror outfit Jaish-e-Mohammed's posters in various locations of the area.
The materials had been recovered during an investigation that recently uncovered a white-collar terror network involving doctors and that was kept in a police station.
Officials said the explosion occurred while police personnel and a forensic team were inspecting the confiscated explosives.
The blast ripped through the structure, severely damaging the station and impacting nearby buildings, leaving the area strewn with debris and panic.
