Eurostar services to and from Brussels and Lille will be cancelled today because of a strike by Belgian workers.
The walk-out by public sector employees will deliver a fresh blow to the cross-Channel rail operator following a fire in the Channel Tunnel last month which has disrupted services.
The 24-hour strike will start this evening, leading to the closure of Brussels Midi station and the rest of the Belgian rail network.
No trains will run between Brussels and Lille, said Eurostar, adding that because of the constraints of the amended timetable caused by the fire, no trains will run between the UK and Lille either.
Eurostar said passengers should change their travel plans. Services are expected to get back to normal after the strike ends.
