Singh was here to unveil a statue of martyr Udham Singh at Jallianwala Bagh.
"Today's IED blast in Sukma, Chhattisgarh is deeply distressing. I bow to each and every security personnel who attained martyrdom while serving the nation.
"My heartfelt condolences to the families of those personnel who lost their lives in Sukma blast. I pray for the speedy recovery of the injured jawans. I spoke to DG @crpfindia regarding the Sukma incident and asked him to leave for Chhattisgarh," he tweeted.
Nine CRPF personnel were today killed after suspected Naxals blew up their mine-protected vehicle in Chhattisgarh's Sukma, around a year after a dozen jawans were killed in a similar ambush in the district. Two other jawans suffered injuries in the attack.
