For Radha Chauhan (37), nightmarish images are still fresh in her mind of splattered blood and people screaming in pain in the December 13 attack 11 years ago when five Pakistani terrorists entered the parliament complex and opened fire at security officials.

“I can never forget the day. It is still fresh in my mind. Whenever I think about the day, I start shaking,” said Chauhan, who was one of the women security personnel at the parliament complex.
