RAIPUR: A commando of CoBRA, an elite unit of CRPF, was injured on Tuesday in an IED blast triggered by Naxalites in Chhattisgarh's Sukma district as polling for the first phase of state assembly elections got underway in the region, police said.

The incident occurred when a joint team of CRPF and Commando Battalions for Resolute Action (CoBRA) 206th battalion was out on an area domination operation from Tondamarka camp towards Elmagunda village to ensure security during polls, a senior police official said.
