Footage has emerged which shows the extent of the destruction to Nairobi's Westgate mall after three floors of the complex collapsed.

Parts of the building crumbled during a four-day siege by suspected al-Shabab militants, which ended on Tuesday.

At least 67 civilians and military personnel were killed in the attack.
