A truck fire has halted rail service through the Channel Tunnel between Britain and France.
Tunnel operator Eurotunnel said Saturday that it had suspended service due to smoke and was investigating the cause. Police say a truck fire at the French end of the tunnel was the source of the smoke. No injuries were reported.
Eurostar, which runs the trains that go through the passage under the English Channel, said the smoke was detected in the north tunnel.
The company said no trains would be running Saturday and recommended passengers "postpone" their travel plans and not come to train stations.
European nations have been on high alert since last week's terrorist attacks in Paris.
