Islamabad, Jan 17 (IANS) Fifteen people were killed and 11 injured Monday in a huge explosion in a passenger bus in Pakistan's Khyber Pakhtunkhwa province. A police official said the blast was caused as the CNG fuel tank burst after an accident.
The blast took place in Kohat town in the bus that was coming from Hangu.
The injured were taken to nearby hospitals.
Deputy Inspector General of Police Masood Afridi told Geo News that the nature of the blast was still not known and he rejected earlier media reports of a suicide attack.
'Two passenger vans collided with each other after which the CNG (compressed natural gas) cylinder of a van exploded,' DPA quoted police officer Abdul Rashid as saying.
'So far, 15 bodies and 11 injured people have been taken to hospital. The death toll might rise since some of the injured are in critical condition.'
