Eurotunnel traffic has resumed after striking ferry workers blocked the tracks leading to the rail link between France and the UK.
French workers torched tyres and blocked traffic as part of their protest against expected job cuts in the French port city of Calais linked to Eurotunnel's sale of its ferry service.
Both freight and Eurostar passenger trains suspended their services for around two hours.
The Eurostar train service carries about 10 million people a year across the English Channel, with summer marking the height of the tourist season.
Striking workers were seen swarming across the tracks, marking the second time in a week port staff had blocked services.
On June 23, they blocked the highway exit leading to the tunnel, prompting migrants who are camped in Calais by the thousands to try and stowaway on the slow-moving freighters in the hope of reaching the UK. Then, later that day, they blocked the tracks themselves.
Traffic resumed the following day.
