Passengers travelling through Calais were warned of delays after a bomb alert was declared at the station.

The station, which serves Eurostar, is in lockdown after the incident this morning, with several busy rail routes ground to a halt, including London-Paris services.

The Pas-de-Calais administration said on social media that a ‘bomb alert’ is underway at Calais-Frethun station.

It said: ‘The situation is being assessed.

‘This may affect traffic in the surrounding area.

‘Please be careful.’

In a subsequent statement, the local government said the situation has been solved and road traffic in the area is about to resume.

Eurostar warned passengers of delays due to the closure of the station ‘at the request of the French authorities.’

‘This is causing delays ⁠to some services to and from ⁠London,’ the operator said when the alert was still active.

However, no Eurostar trains have been listed as delayed on its status update, where the operator said ‘due to a request for police assistance at Calais-Fréthun, your train is delayed.’

The latest alert comes after a spate of hoax bomb warnings across schools in the UK and Europe yesterday.

Schools in Italy were evacuated after around 6,300 of them were sent bomb warnings.

Flights were also disrupted last week after bomb threats across the continent, grounding planes at several airports as a precaution while aircraft were searched.
