Naxalites late Wednesday fired at three CRPF camps in Chhattisgarh simultaneously, prompting the troops to retaliate, but no casualty was reported.
The firing which started at around 2130 hours at the CRPF camps at Narayanpur, Dantewada and Bijapur districts, went on for an hour, senior CRPF officials said adding, it was carried out by Naxalites to "provoke" the troops.
At Narayanpur, which saw an ambush by Maoists on June 29 killing 27 security personnel, Naxals fired at the 39th battalion camp of the force near Edka village. The other two firing incidents took place at Polampalli in Dantewada and Basaguda in Bijapur districts.
"Ten rounds have been fired from both the sides and the firing took place from a distance at Narayanpur," district Superintendent of Police Rahul Bhagat said.
The Naxals fled the sites when security forces returned fire, officials said.
