Traffic has resumed in the tunnel beneath the English Channel, but lines are still long for trucks traveling between Britain and France following a day of disruption by striking port workers.
Illegal migrants trying to cross into Britain are taking advantage of the snail's-pace traffic to sneak onto trucks boarding the shuttle trains that carry them through the tunnel.

A passing motorcyclist captured images of migrants gathered near trucks waiting to pass through the tunnel.
On Tuesday morning, Britain's Prime Minister David Cameron met with the home secretary and transport secretary to discuss the situation at Calais.
Eurotunnel, which runs those shuttle trains, said traffic resumed Wednesday morning, as did the Eurostar passenger train service.
Both companies cancelled all trains Tuesday after ferry workers striking over expected job cuts swarmed train lines and set tires alight.
Good Morning! Trains are running to schedule today, if travelling with us please arrive in advance allowing 45 minutes for check in.— Eurostar (@Eurostar) June 24, 2015
Migrants from Sudan, Eritrea and elsewhere are camped by the thousands in the port city of Calais trying to reach Britain, where they believe they will have better job prospects.
