A woman has been killed in a fire which broke out in her bedroom inside a block of flats in Oxfordshire.
Smoke and flames were spotted coming from the window of the first-floor property in Kibble Close, Didcot, just after 0200 GMT.
The woman, who was in her 40s, died at the scene.
Neighbours, who were led to safety by firefighters, tried to rescue the woman but were forced back by thick black smoke.
An investigation has been launched into the cause of the fire, which is not being treated as suspicious.
Firefighters spent four hours at the scene and a cordon has been put in place.
The flat was fitted with a smoke alarm.
Station manager Mick Pilcher, of Oxfordshire Fire and Rescue Service, said: "The bedroom had a fully-developed fire in it which could be seen through the window of the first floor-flat and the smoke was very black.
"Neighbours heard the smoke alarm and were trying to help to get her out of the flat.
"They couldn't get in and were trying to raise the alarm."
