Hurricane Sandy: Bloomberg says 'we have done all we can'

New York City Mayor Michael Bloomberg says that he thinks "we have done all we can to prepare" as Hurricane Sandy approaches.

Authorities warned that high tides triggered by a full moon could create storm surges of up 11ft (3m), sending seawater surging through parts of lower Manhattan.

Hurricane Sandy is bearing down on America's most densely populated region, with storm surges and flooding forecast up and down the East Coast.

Thousands have been ordered to evacuate New York City and New Jersey. The storm could affect 50 million people.
