Powerful storms are barrelling down on the southern US for a second night, raising 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.

Several tornadoes flattened buildings, overturned vehicles and brought down utility lines on a second consecutive night of devastation.

At least 16 people died in Arkansas, Iowa and Oklahoma on Sunday night.
