US snowstorm warnings as blizzards hit north-east coast

A winter storm on America's north-east coast has brought near-whiteout conditions and lightning strikes in coastal areas.

Blizzards have forced the cancellation of more than 1,750 passenger flights, most of them into and out of airports in Boston and New York.

For residents of Boston, the latest storm has made February the snowiest in the city's history.
