Government taking attack on CRPF by Naxals as challenge: Rajnath

"We have taken the attack as a challenge," Rajnath told reporters here. Singh described the incident as "sad and unfortunate". 

"It is a very sad and unfortunate incident. I will talk to Chief Minister Raman Singh for more details," he said. 

Earlier, Singh asked Minister of State for Home Hansraj Ahir to travel to Chhattisgarh to take stock of the situation. 

"Extremely pained to know about the killing of CRPF personnel in Sukma. My tributes to the martyrs and condolences to their families," Singh tweeted. 

At least 26 CRPF personnel were killed and six wounded in Sukma district today, the deadliest attack by Naxalites targeting security forces this year.
