Security camera footage obtained by Reuters shows the Westgate shopping mall in Nairobi moments before gunmen enter the building September 21st.
It looks like any day in a mall.
Then people turn their heads towards an entrance and flee.
A woman appears to investigate the scene and suddenly takes off.
Later a man takes cover behind an elephant that is part of a display. Gunmen enter the scene and what follows is too disturbing to air as the man is shot at point blank range. He is later seen struggling for his life, his blood smeared on the floor.
Another camera captures a scene from a restaurant. One person appears wounded as others huddle behind a counter.
About 60 people died in the four day siege that followed. Some are still missing.
Kenya has accused the Somalia group al-Shabaab of being behind the attack.
