Winter storm brings havoc to US east

A winter storm of "historical proportions" is bringing large quantities of snow to the US north-east, after gridlocking traffic and causing power cuts across the south.

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.
