A 15-year-old girl has died and two people are in critical condition after a collision between a minibus and a lorry on a motorway in southern Scotland, police have said.
The youngster, one of six passengers in a red Ford Transit Tourneo minibus, died in hospital after the vehicle collided with a white lorry, then hit the central reservation near junction 20 of the M74.
The bus was travelling northbound, at around 4.45pm on Wednesday.
The girl was taken to the Cumberland Infirmary in Carlisle but later lost her life, Police Scotland said.
A 17-year-old boy and a 42-year-old woman were both flown to hospital by air ambulance in a critical condition.
He was admitted to the Royal Victoria Hospital in Newcastle, while she was taken to James Cook Hospital in Middlesbrough.
A six-month-old girl, a seven-year-old boy, a 12-year-old boy and the 45-year-old man driving the minibus, suffered minor injuries and were all taken to the Cumberland Infirmary.
