Hurricane Sandy

Hurricane Sandy is bearing down on the US East Coast, threatening serious flooding and power cuts that could affect 50 million people.

Hundreds of thousands of residents have been ordered to evacuate New York City and New Jersey.
Public transport has been suspended in cities up the eastern seaboard and thousands of flights grounded.
Forecasters fear Sandy will become a super-storm when it collides with cold weather fronts from the west and north.
The category one hurricane coincides with a full moon, which is bringing higher tides.
At the White House, President Barack Obama warned Americans in harm's way to follow emergency instructions.
"Do not delay, don't pause, don't question the instructions that are being given," said Mr Obama, who has cancelled campaign events, eight days before the US elections.
"This is going to be a big storm, it's going to be a difficult storm."
