A boy and a girl under the age of three were killed with their parents in a head-on collision between a car and a lorry.
The four family members were killed when their Fiat collided with an articulated lorry on the A801 near Polmont, on the outskirts of Falkirk in Scotland, at about 2.20pm yesterday.
The mother and father were in their 20s while their boy and girl were under the age of three, police said.
Their car had crossed into the path of oncoming traffic before the crash.
The lorry driver was treated at the scene for shock.
