An Eritrean migrant suffered a head injury after attempting to get into Britain on 24 August. The 22-year-old is believed to have been hit by a train in northern France as he was attempting to make his way inside the Eurotunnel.

"Around 10 this morning, firemen went to Eurotunnel's boarding platforms to tend to an injured migrant," said local authorities, reported France24 News.

"He was immediately hospitalised in Calais and he is in a serious condition." The migrant was later reported out of danger despite suffering from internal bleeding.

Meanwhile, a Eurostar train was delayed on 24 August after several migrants reportedly entered the Channel Tunnel.

As the Calais migrant crisis grows into a bigger challenge for the European Union, leaders from France and the UK recently met to work on a new joint deal. Home Secretary Theresa May met with her French counterpark Interior Minister Bernard Cazeneuve and visited the Eurotunnel.

Amongst the measures announced to tackle the growing migrant population in Calais, the leaders announced a joint command centre in the town.
