Polar vortex claims eight lives as US cold snap continues

At least eight people have died in the US Midwest as the region shivers in the grip of its worst cold snap in decades.

An Iowa student found dead outside a college building is among the victims of the deadly freeze.

Hospitals have been treating patients reporting frostbite as life across a swathe of the nation grinds to a halt.

The iciest blasts may still come on Thursday. Ninety million people - a third of the US - have seen temperatures of -17C (0F) or below.

Some 250 million Americans overall have experienced the "polar vortex" conditions, but southern states such as Florida have escaped the brutal chill.

How did the fatalities occur?

University of Iowa student Gerald Belz, 18, was found unresponsive behind a campus building before dawn on Wednesday and later died in hospital. Officials said weather was a factor. His father told local news channel KCRG that Gerald was a "mama's boy with a tough exterior".
