At least seven people are now known to have died in a fiery motorway pile-up in the southwest of England.
More than 50 people are in hospital, with at least 10 reported to be in a critical condition. Police warn the death toll is likely to rise.
The accident happened on the busy M5 motorway and involved more than 30 cars and trucks.
Witnesses say a fireball that engulfed numerous vehicles hampered initial rescue efforts.
The accident near Taunton in Somerset happened in wet and foggy conditions.
One motorist at the scene said: “It is an absolute tragedy, you just can’t think what people are going through, just waiting to see what has happened or who is in the wreckage.”
Another man said: “We were driving down the road and saw what we thought was a bonfire. But obviously it transpired to be vehicles that were on fire.”
An investigation will also examine whether a nearby fireworks display might have played a part in the tragedy.
The M5 is closed in both directions and police say it could remain shut until Sunday.
