Begum, who left the UK in December 2014 while still a teenager, became one of the earliest British schoolgirls to travel to territory controlled by Isis. She attended Bethnal Green Academy in Tower Hamlets and has long been associated with the radicalisation of fellow pupils, including Shamima Begum, who travelled to Syria in February 2015 alongside friends Amira Abase and Kadiza Sultana.
