A 34-year-old woman who was seriously injured in a head-on car collision which claimed the lives of six others has died, police have said.
The road is not known as an accident blackspot, said police
The woman's 10-year-old nephew and nine-year-old niece are the only survivors of the crash which killed their grandparents and four others.
It happened on the A429 between Moreton in Marsh and Stow on the Wold in Gloucestershire on Friday night.
Police have described it as one of the "worst ever" collisions in the county.
The cars involved - a Peugeot 306 and a VW Passat - crashed head-on as the Peugeot tried to overtake another car, said a Gloucestershire Police spokesman.
The children's 53-year-old grandfather - who was driving the Passat - died at the scene.
Their grandmother, 61, died later in hospital. She had been in the front passenger seat.
The children's aunt - a 34-year-old woman from Stow-on-the-Wold - died in hospital on Saturday night.
The two children, from Stow, are described as being in a critical condition and are both being treated in hospital in Bristol.
They, like their aunt, had been rear-seat passengers in the VW Passat.
Four people in the Peugeot died at the scene. They were a 35-year-old man, a 31-year-old woman and a 15-year-old girl - all from Moreton-in-Marsh - and a 20-year-old man from Chipping Norton.
Neither of the female occupants of the car that was overtaken was hurt.
