A man and a woman from Devon have been taken to hospital with carbon monoxide poisoning.

Incident Commander Nigel Deasy, Devon and Somerset Fire and Rescue Service.
Fire officers have praised a family for their actions after a fire destroyed their home near Cullompton.
Working smoke alarms alerted the family to the danger when the blaze started in the kitchen of their end-of-terrace property, and they were able to leave their home quickly and safely.
A closed internal door also helped delay the spread of the fire while the four children and their father left the house without stopping to pick up possessions. Two dogs and a cat also left the property safely.
Five people have been saved from a house fire in Bradninch near Cullompton, Devon. They were rescued by crews who were called out just before 3am. Two children have been taken to hospital with breathing difficulties.
