Samuel Wendt left his home in Germany in September 2014 and went to live in Syria for three months, in the so-called Islamic State.

He says why he made that decision and how he wanted to offer humanitarian assistance to people caught up in the fighting there.

He was speaking to Victoria Derbyshire programme reporter James Longman, via Connect Futures - a British social enterprise which specialises in tackling extremism.
