Nov. 15 (UPI) -- At least nine died and 32 were injured at a police station in Kashmir when officials accidentally triggered an explosion while examining materials used to make bombs.

The materials were to undergo forensic examination, but a "very unfortunate" incident caused them to explode shortly before midnight on Friday, regional Director-General of Police Nalin Prabhat told media.

"Any speculation into the cause of this incident is unnecessary," Prabhat said, without detailing how the deadly detonation occurred.

The explosion happened in Nowgam in the India-administered province as police inspected the materials that they seized while investigating a terrorism network, The New York Times reported.

The 6,000 pounds of materials and other weapons were seized in Faridabad while investigating a car bomb that killed eight in the Indian capital of New Delhi on Monday and has been deemed a terror attack.
