Six Central Reserve Police Force personnel, including an inspector, were killed in a landmine blast triggered by Naxals in Chhattisgarh's Narayanpur district on Friday.

The incident occurred on a state highway when the CRPF team was proceeding on an anti-Naxalite operation from Konda to Narayanpur at around 11 am, CRPF spokesman Ajay Chaturvedi said.

The CRPF vehicle carrying the team was blown up in the explosion. Combing operations have been launched to nab the Maoists involved in the blast.

The CRPF has despatched Deputy Inspector General of Police R S S Sahota to Narayanpur for an on-the-spot assessment of the situation.

Terming the incident as very unfortunate, Director General of CRPF V K Joshi said anti-Naxal operations have been intensified under the supervision of senior officials.

The inspector killed in the blast has been identified as R S Kang.
