Train services through the Channel Tunnel between Britain and France have been suspended after a serious fire.
The fire broke out on a truck being carried on a railway carriage 11km from the French entrance to the tunnel. Passengers on the train were safely evacuated, Eurotunnel spokewoman Mady Chabrier said.
The French Interior Ministry said a chemicals truck had caught fire, while French rail operator SNCF said rail traffic through the tunnel was suspended. The truck was carrying phenol, a toxic product used by the pharmaceutical industry.
Six people were treated for injuries and smoke inhalation, according to government officials at the scene.
Eurostar, which carries an average of 22,000 people a day through the tunnel, said it couldn't guarantee services would resume tomorrow.
The company said it had implemented a policy of exchange or refund for people who did not want to travel after the incident.
The tunnel was severely damaged in a major fire on a shuttle train carrying lorries in 1996. That fire burned for several hours, wrecking the concrete lining and facilities over around half mile of tunnel and causing £200 million worth of damage.
