Eurostar passenger services have resumed through the Channel Tunnel after a smoldering load on a truck triggered an alarm that shut down services and caused severe disruption for thousands of passengers.

Freight services also resumed early Sunday between England and France in the south tunnel. John Keefe, the spokesman for tunnel operator Eurotunnel, said the freight train affected by Saturday's incident must still be removed from the north tunnel.

Keefe says Eurostar passenger services are being given priority, but that delays will take place. Eurostar says to expect delays of between 30 and 60 minutes.

C02 alarms detected the smoke in the tunnel Saturday, touching off the shutdown at around midday.

Eurostar has said tickets can be refunded or rebooked within the next 60 days for travel within six months.
