(BBC) In 2013, Nasser Muthana and Reyaad Khan left their lives in Cardiff to fight for Islamic State in Syria.
Three months later Nasser’s younger brother Aseel also went out to join them.
I went to sixth-form college with both Nasser and Reyaad, and Aseel had gone to my school.
I recently travelled to Syria for BBC Panorama to try and speak to Aseel and to find out why they left Cardiff to join such a brutal organisation.
Aseel Muthana
Aseel was pleased to see me. He’s spent two years in a crowded cell in north-east Syria. He is being held by the Kurdish forces who captured Islamic State group members at the last bloody battle of Baghuz.
