Around 15 cops were injured when a mine protected vehicle of C-60 commandos, the Anti-Maoist squad, came under a landmine attack near Bhamragarh in Gadchiroli on Wednesday night.
The incident occurred when the C-60 patrolling party was crossing the area. Maheshwar Reddy, the additional superintendent of police, Gadchiroli, said those who received minor injuries were rushed to the nearest civil hospital, but three, who were grievously hurt, were airlifted to Nagpur for treatment.
Reddy said additional police forces were sent to the area and a massive combing operation is on to flush out the ultra-left activists.
Earlier in the day, a CRPF jawan and two state police personnel were injured in a firing with the militants in south Gadchiroli. The police also seized huge arms and ammunition from the site.
The Maoists had targeted a CRPF team near Sukma on April 24 in Chhattisgarh and killed 26 paramilitary jawans. Similarly, the ultra-left extremists killed 12 CRPF personnel in another attack in Sukma on March 11 this year.
