A minibus driver has been arrested after a crash in which a boy, aged seven, died.
Ambulance crews were called to a collision on the A466 Hereford Road in Monmouth at about 15:50 GMT on Monday.
The bus driver, a man, 45, from Gloucester, was arrested on suspicion of causing death by careless driving.
A spokeswoman from West Midlands Ambulance Service – which attended the scene along with crews from Wales – said the boy was a pedestrian.
She said: “Sadly, nothing could be done to save him and he was confirmed dead on scene.”
Gwent Police closed the road between Withy Lane and Buckholt for several hours following the incident.
The driver remains in custody while police appealed for witnesses.
