A bomb alert at a French train station disrupted journeys including international travel, with Eurostar trains among those affected.
The incident at Calais-Frethun, a station in northern France, affected rail traffic including trains between London and Paris on Thursday morning.
A Eurostar statement said: "At the request of the French authorities, trains are currently unable to pass through Calais-Frethun station.
"This is causing delays to some services to and from London."
But train services resumed later in the morning after the gendarmerie authorised their restart, national train operator SNCF said.
The national gendarmerie did not immediately respond to an emailed request for comment.
The alert came amid a broader wave of bomb threats and hoaxes reported in France and other European countries in recent months, targeting flights, schools and, in some cases, media organisations.
It was not immediately clear whether Thursday's alert was linked to any of the previous threats.
