Two elderly couples have been rescued after a carbon monoxide leak in a stove in a north Devon home.
Firefighters said the couples were 'incredibly lucky'
One man woke up feeling poorly and collapsed. Another man managed to call the emergency services before also collapsing at about 0400 BST.
High levels of carbon monoxide were later detected in the solid fuel stove at the house in Burrington, Umberleigh.
All four occupants were taken to hospital suffering from suspected carbon monoxide poisoning.
A spokesman for Devon and Somerset Fire and Rescue Service said the couples were "incredibly lucky".
Two fire engines, gas detection equipment and a hazardous material officer were called to the property.
