Police have arrested a woman after two young boys died in a house fire in Wolverhampton.
Emergency services were called to Mason Street at around 8.30pm on Friday after a blaze broke out at a house in the area.
West Midlands Police said the boys, aged one and three, were found at the scene and pronounced dead despite ambulance crews giving them advanced life support.
The force said a woman in her 30s has been arrested on suspicion of causing or allowing the death of two children and remains in custody.
Two other children and a woman had already got out of the property before emergency services arrived and did not need hospital treatment.
Police are continuing to work with fire investigators to establish exactly how the blaze started and what happened in the moments before it.
Officers are carrying out door-to-door enquiries and reviewing CCTV from the area as part of the investigation.
A cordon remains in place at the scene and police have said it is likely to stay there for some time.
Detective Chief Inspector Kylie Westlake, from the public protection unit, said: “This is a truly tragic incident and our thoughts remain very much with those who loved the children who have been lost.”
She added that officers are working at pace to understand the full circumstances and urged people not to speculate while the investigation continues.
Police have asked anyone with information who has not yet spoken to officers to come forward.
