Hundreds of Eurostar passengers have been left stranded in dark, stifling trains after "intruders" climbed onto the tracks, in the latest disruption to the cross-Channel service by suspected asylum seekers trying to reach Britain, reports ABC News.
A Eurostar official said water and food had been distributed to passengers on the 9055 train from Paris to London, which remained at the Calais-Frethun station in northern France at 5:00am (local time).
"Rescue services are also present for those who need help, particularly the elderly," added the official, describing the situation as "complicated".
Five other trains originally disrupted by the incident were either been sent back to where they departed from or on to their final destination.
The Calais-Frethun station lies close to the port of Calais, where some 3,000 asylum seekers living in makeshift camps have been ramping up their attempts to outfox hopelessly outnumbered security officials and police to reach what they see as the El Dorado of Britain.
A passenger aboard the train, Géraldine Guyon, said the situation remained tense.
