[Ed. – I think we’ve identified this as a crisis, at this point.]
Chaotic scenes and 16 hour delays hit London-bound Eurostar services overnight as migrants climbed on to the roof of an 186mph train and attempted to break into train carriages.
Passengers on board one train stranded near Calais are understood to have threatened to smash the windows after a power outage left the sweltering carriage in total darkness for five hours.
The power failure also saw those on board left without air conditioning and unable to communicate with Eurostar staff before the stricken train eventually returned to Paris.
As they searched in vain for the migrants, Eurostar staff went as far as making the bizarre move of appealing to passengers to listen out for the sound of movement on the roofs of the trains.
At least four UK-bound trains were delayed for several hours, with two of them sent back to Paris, as police attempted to remove the trespassers from the tops of carriages in Calais.
