Airports have been struggling to cope with a backlog of flights, as record-breaking temperatures continue to freeze parts of the US and Canada.

The region is in the grip of an Arctic blast with a storm that has brought snow, hurricane-force winds and coastal flooding.

Temperatures have been so cold that some authorities have warned residents that they risk frostbite if their skin is exposed for just 10 minutes.

Mount Washington, New Hampshire, recorded a temperature of -37C (-35F) on Saturday morning, with a wind chill of -69C (-93F) - making it the second-coldest place on Earth with Armstrong, Ontario.

The coldest temperature was recorded at -39C (-38F) in Eureka, Nunavut, in Canada and Jakutsk, Russia.
