A Central Reserve Police Force vehicle was slightly damaged when a civilian car exploded near a convoy on the Jammu-Srinagar national highway in Ramban district of Jammu and Kashmir on Saturday, The Indian Express reported.

The blast is believed to have taken place after one of the gas cylinders of the Santro car caught fire, PTI reported, quoting police. The incident took place at 10.30 am.

The Central Reserve Police Force said no one was injured in the blast and that officials were investigating all angles. “An explosion took place in a civil car near Banihal while the CRPF convoy was on move,” a spokesperson said. “The car caught fire and slight damage was caused in the rear of one of the CRPF vehicles.”

Inspector General Police of Jammu zone MK Sinha said an unexploded cylinder was also found at the site. A search operation is underway. The driver of the car was missing from the spot, an official told Greater Kashmir.

“It has not been established whether it was a [terror] attack or not,” Governor Satya Pal Malik said. “It has also not been established why the vehicle caught fire. No explosive of sorts, but nothing can be said [at the moment].”
