Eurostar passenger: 'It's a shambles'
A strike forced the suspension of services through the Channel Tunnel between the UK and France on Tuesday, as hundreds of migrants tried to board UK-bound lorries amid the chaos.
The tunnel was shut after striking workers gained access to the tracks and caused a fire, Eurotunnel said.
Eurotunnel says its passenger services resumed from 17:50 UK time (16:50 GMT) with two departures per hour, but that they would run with a delay of at least two hours in both directions.
The Eurostar train company, which also uses the tunnel, said trains would not be able to run for the rest of the day.
Passengers at St Pancras International station in London described their frustration at the suspension of services.
