The three injured commandos were airlifted to a hospital in Ranchi, he said, adding that their condition is stable. Acting on a tip-off that a large number of Maoists have gathered, a search operation was started in the forest on Wednesday. Soon, a gunfight broke out between the security forces and the Maoists, police said. The Maoists, who were retreating, triggered an IED blast, injuring the six commandos, they said.
