A tornado has hit southern parts of the US state of Georgia, killing 11 people.

The US National Weather Service is warning there could be more tornado activity throughout the day across Georgia, Florida and South Carolina.

This follows on from four tornado-related deaths which occurred in Mississippi on Saturday morning.
