An explosion and gunfire were heard at the Westgate complex on Tuesday morning, but later a senior police source said the operation was "over".
At least 65 people have been killed, including three soldiers.
Ajay Patel was outside the centre on Saturday, and told Jon Sopel on BBC World News that he saw the attackers unloading weapons.
