US tornadoes: Footage shows aftermath of 'chaos'
Powerful storms have caused damage across parts of the southern US, pushing the death toll above 20.
Six deaths were reported in Alabama and seven in Mississippi after tornadoes struck on Monday evening, although not all these fatalities were confirmed.
Tornadoes have flattened buildings, overturned vehicles and uprooted trees, something which one resident described as "chaos".
