Syrian refugees: The journey across Europe

This year has seen an unprecedented number of migrants arriving in Europe.

Most have come from Syria, where four years of civil war has claimed more than 200,000 lives.

The BBC has been following their journeys across Europe.

Chris Buckler reports from the Greek island of Lesbos, where many of the Syrian refugees first set foot.

From Serbia, Ed Thomas reports on the long march to western Europe.

And Tom Burridge reports from Berlin, where thousands have been granted asylum.
