‘All terrorism is about the spread of hatred… If we hate, they win’, says brother of Islamic State victim David Haines

Alexanda Kotey was one of the so-called Beatles, an Islamic State cell of four British men that tortured and murdered mainly western hostages in the mid-2010s.

At his sentencing, one of the most moving testimonies came from Mike Haines, whose brother David was an aid worker killed in 2014.

Our Washington correspondent, Siobhan Kennedy, met Mike to get his reaction after Alexanda Kotey was jailed for life in a US court.
