Migrant crisis: The fence being built to keep the migrants out
The number of migrants trying to reach Europe is continuing to rise, with many travelling through Hungary in an effort to get into the EU's passport free zone.
More than 120,000 migrants have arrived there this year, triple the number in 2014.
In an effort to stem the flow, the government in Budapest is building a 110 mile long fence along its border with Serbia.
