A Syrian refugee has died after being electrocuted at the entrance to the Eurotunnel in Calais, French police said.
The man (25) was killed when he touched a power cable while attempting to jump on to a high-speed training heading through the Channel tunnel.
Currently there are more than 3,500 refugees - many fleeing conflict in Sudan, Eritrea and Syria - living in makeshift camps near the French port of Calais.
In recent weeks new security measures introduced at the tunnel entrance have led to a fall in intrusion attempts.
Eurotunnel confirmed that a freight train was stopped at about 22:20 on Thursday because of the presence of migrants on the tracks.
When the train was searched, a number of migrants were found on board, with one unconscious and one injured, the company said in a statement.
They were immediately taken into care by the emergency services. The authorities later confirmed the death of one of the migrants."
“This sad incident shows once again that any attempt to travel illegally through the Channel Tunnel is fraught with danger," Eurotunnel said.
The situation in Calais comes as Europe struggles to cope with the huge numbers of people heading north from the Mediterranean.
On Thursday, Croatia announced it was closing seven of its eight road border crossings with Serbia following a huge influx of refugees.
Officials said they had no choice after more than 13,000 people entered the country since Hungary fenced off its border with Serbia earlier this week.
It was a far cry from what they had left behind - after a week stranded in squalid limbo outside Budapest's main railway station, thousands of refugees crossed from Hungary into Austria yesterday and received something they had been missing: a warm welcome.
