A two-year-old boy has died and his six-year-old brother is critically ill after a suspected hit-and-run crash in Coventry.
They were struck by a car on MacDonald Road, Stoke, at about 14:00 GMT and taken to hospital with life-threatening injuries.
A 53-year-old man and a 41-year-old woman have been arrested on suspicion of causing death by dangerous driving.
A black Ford Focus was found abandoned a short time after the crash.

Det Sgt Paul Hughes, from West Midlands Police’s collision investigation unit, said the force was “trying to establish how this tragic incident has happened”.
“This is a parent’s worst nightmare and it’s impossible to imagine their grief, but specialist officers will be supporting them as our investigation continues,” Det Sgt Hughes said.
Police officers have been speaking to witnesses at the scene and the road remains closed.
West Midlands Ambulance Service (WMAS) said the two-year-old boy was taken to University Hospital Coventry and the six-year-old was taken to Birmingham Children’s Hospital.
WMAS sent four ambulances, two paramedic officers and a critical care car from the air ambulance service.
The air ambulance crew accompanied the six-year-old as he was taken to the children’s hospital to administer specialist treatment.
A local resident, who preferred not to give her name, said the aftermath of the crash included a “smashed” pushchair in the road alongside a child’s scooter.
She said: “The police had taped the road off and there was debris all over the road.”
Labour city councillor for Wyken, Faye Abbott added: “We’ll all be very sad and thinking of the families of those who have been involved in this accident and hoping that the little boy makes a full recovery.”
