A British jury has found three young men guilty of helping a friend travel to Syria to join the Islamic State group.

Kristen Brekke, Adeel Ulhaq and Forhad Rahman will face prison sentences for helping the 17-year-old jihadi follow in the footsteps of his big brother.

Aseel Muthana left home in Cardiff, Wales, on Feb. 21, 2014, to join his older brother, Nasser, among the fighters for Islamic State. Prosecutor Annabel Darlow says the men shared a "highly radical ideology," supporting war in Syria.

Nasser Muthana had traveled to Syria just a few months ahead of this brother and later became known for a propaganda video called "There is No Life Without Jihad."
