Naxalites tonight opened fire at CRPF camps in Chhattisgarh's Sukma district but the attack was repulsed by security personnel.
Sources said three different camps of the paramilitary in south Bastar were targeted in Naxal gunfire which was suitably retaliated to by the troops.
The firing went on for about an hour, they said. There has been no loss of life or property.
"This is Maoists' regular strategy to aim and fire at security forces camps from a distance and then run away in the dark," a senior official said.
The forces are on alert everywhere in the state, the official said.
The security forces have been on an hightened alert following the May 25 Naxal ambush in Bastar that killed state PCC chief Nand Kumar Patel and prominent Congress leader Mahendra Karma.
Twenty-five other party workers and locals were also killed in the deadly encounter which wiped out the top Congress leadership of Chhattisgarh.
