The death toll from Sandy keeps rising as swathes of the US East Coast battle to recover, three days after being smashed by the massive storm.

More than 80 people are now known to have died, 37 in New York City alone, and others remain missing.

About 4.6 million people are still without power, and there are fuel shortages across the region.

The National Guard is to deliver a million meals and bottled water to New Yorkers affected by the storm.

The number of dead in the US has exceeded the toll from the Caribbean, where 69 people were killed by Sandy.

The storm could cost the US $50bn (£31bn), according to forecasting firm Eqecat, doubling the previous estimate.
