Two US boys whose parents became alarmed when they did not come home from playing in the snow were found hours later buried in a snow bank.
Officials say a snowplough operator in Newburgh, New York, who was moving snow did not realise they were there.
The authorities say the parents of the boys, aged nine and 11, called police just before midnight local time on Wednesday. The children had been out, possibly trying to build a snow fort.
Officials searching a snow bank nearby found the boys around 2am yesterday. They were conscious and suffering from exposure. The boys were taken to the hospital, where one remains under observation.
Authorities say a snowplough operator had been clearing a car park by pushing snow over, and did not see the boys on the other side of the pile.
