Al Shabab Militants Rented Shop From Nairobi Mall Weeks Before Attack

Stockpiled weapons

The militants who led the attack on a Kenyan mall hired a shop there in the weeks leading up to the siege, senior security sources have told the BBC.

This gave them access to service lifts at Westgate enabling them to stockpile weapons and ammunition.

Having pre-positioned weapons they were able to re-arm quickly and repel the security forces.
