No casualty was reported in the blast which took place at around 11 am near Jamdi village, a senior police official said.
A joint team of Indo Tibetan Border Police (ITBP) and District Force had organised a flag hoisting programme at Koracha village, located around four kms deep in the forest under Kohka police station area (which is around 200kms away from the state capital), to celebrate Independence Day with the villagers, Rajnandgaon's Superintendent of Police Prashant Agrawal told PTI.
"No one was harmed in the blast as it occurred at some distance away from the security personnel," the SP said.
Following the incident, a combing operation was launched in the region to trace the attackers during which another IED was recovered from the area, he added.
