A huge winter storm is affecting the densely populated US north-east, after wreaking havoc in the south.

Across the typically mild south, more than half a million homes and businesses lack power, and more than 3,300 flights have been cancelled.

The storm is expected to affect people in 22 states from Texas to Maine.
