This concludes our live coverage of the disruption to Channel Tunnel services today.
Services remain suspended after smoke was detected by two CO2 detectors in the south tunnel at around 11:25 GMT.
A load on a lorry on board a train, en route from the UK to France, had been "smouldering", a Eurotunnel source said. No-one was hurt in the fire.
Eurostar, which operates passenger trains, has cancelled all its services for Saturday, while Eurotunnel says it expects to resume vehicle and freight services on Saturday night.
