Nine people were killed and 31 injured when confiscated explosives accidentally blew up at a police station in Indian-administered Kashmir, police said yesterday, just days after a car blast in Delhi killed a dozen people.

The incident happened in Nowgam and the explosives at the police station were recovered from Faridabad in the northern state of Haryana earlier this week, just hours before the powerful blast in Delhi that killed 12 people.

Samples from the recovered material were being sent for further forensic examination since Thursday, the region's director general of police Nalin Prabhat said, and the procedure was being handled with "utmost caution" due to its "unstable and sensitive nature".

"However, unfortunately during this course (on Friday) around 11:20pm, an accidental explosion has taken place. Any other speculation into the cause of this incident is unnecessary," he told reporters.

The victims included police personnel, forensic team members and two crime photographers and other members from the local administration.

"The building of the police station has been severely damaged and the adjacent buildings have been affected," he added.

Local media reported that the militant organisation People's Anti-Fascist Front (PAFF), said to be close to the Jaish-e-Mohammed (JeM) group, had taken responsibility for the explosion, but the region's police dismissed the claims.

"The claim of PAFF or any other Pakistani terrorist group is patently false, baseless and mischievous!" the Jammu and Kashmir police said in a post on X.
