The CRPF personnel were on routine patrolling in Palodi in Kishtaram area of Sukma district when the Naxalites set off an improvised explosive device (IED), blowing up the vehicle at around 11 a.m., Sinha said. "Extra force has reached the spot, there is no firing at present". Officials added that the first encounter took place at 8 am and later this contingent was targeted.
Chhattisgarh Chief Minister Raman Singh has also demanded a full report on the attack. He also said that the Sukma incident was "deeply distressing".
Congress President Rahul Gandhi said the killings of CRPF soldiers was indicative of "deteriorating internal security situation due to flawed policies" of the Centre's Narendra Modi government. "I spoke to DG crpf regarding the Sukma incident and asked him to leave for Chhattisgarh". The deceased CRPF personnel are from the 212 battalion.
"The martyrdom of security personnel who sacrificed their lives while discharging their duties will always be remembered", the chief minister said in a statement.
Twelve jawans were killed on March 11 past year in the Bheji area of the district and their arms looted, when Maoist ambushed their patrol party.
The incident happens around a year after a dozen jawans were killed in a similar ambush in the Sukma district.
