The violence and desperation at the Serbia-Hungary border is another reminder of the risk so many people are taking in their quest to reach Western Europe.
I've been on the road, following the migration route through Hungary, Austria and into Germany.
I wanted to find out more about the people travelling through Europe. Who are they? What is their profession? How did they get here? Where are they going?
And to ask: What drives a person to leave their home and everything they know behind and set off on a very long journey in search of a new life?
Here are some of the stories I found along the way.
RAAFAT: 37
HOME: DAMASCUS, SYRIA
DESTINATION: NORWAY
At the border crossing from Serbia into Hungary I meet Raafat from Damascus in Syria. He wants to build a new future with his son in Norway. His journey has taken him via Lebanon and Turkey, where he says he swam at night for seven hours to reach Greece and Europe.
FADI: 38
HOME: DAMASCUS, SYRIA
DESTINATION: GERMANY
I find Fadi taking shelter from the rain in a tent near Roszke. He's a professional artist from Damascus in Syria. He's travelling with his Nephew and wants to go to Germany. He left Syria 9 months ago, and took a boat from Turkey to Greece before travelling up through Macedonia and Serbia.
MUSTAFA: 14
HOME: IDLIB, SYRIA
DESTINATION: GERMANY
In the refugee camp at Roszke in Hungary, 14-year-old Mustafa tells me his story through the fence. He's from Idlib in Syria where he says he went to school every day, until the building was destroyed by a bomb. He wants to go to Germany to be "free" and go to school.
AHMED: 19
HOME: ALEPPO, SYRIA
DESTINATION: GERMANY
At the border crossing between Hungary and Austria 19-year-old Ahmed is travelling with his mother, brother and little sister. He says they lost their home in Aleppo in Syria and escaped to Europe via Turkey by boat. He wants to go to Germany to study and become a dentist or a doctor.
