ROUGH CUT (NO REPORTER NARRATION)
Fresh CCTV images obtained on Friday appear to show up to five armed gunmen walking around a Nairobi shopping mall, the site of a deadly siege by Somali al Shabaab Islamists, on the day the attack began.
The footage of Westgate mall from September 21 shows armed people walking around the Nukumatt supermarket, some of whom have covered their faces.
The Kenyan television station that provided the footage said it had been released by the Kenyan Military.
The assault on Westgate mall in the Kenyan capital killed at least 71 people, including foreigners.
The militants stormed the mall, known for its Western shops selling iPads and Nike shoes, in a hail of gunfire and grenades at lunchtime on September 21.
