Teenager 'critical' after M90 crash
An 18-year-old man is in a critical condition after the car he was travelling in overturned on a motorway sliproad near Perth.
The male driver, 20, was also seriously injured in the crash at Junction 10 of the M90 at about 0005 GMT, police said.
Both men were trapped in the grey Ford Focus and had to be cut free by firefighters.

Tayside Police said the car had overturned on the sliproad leading from Edinburgh Road to the motorway junction.
A spokesman said: "A full inquiry has been launched and the road was closed whilst crash investigators completed their investigations at the scene."
Officers are appealing for witnesses - or anyone who saw the car prior to the crash - to come forward.
