Dr Abbas Khan travelled to the Syrian city of Aleppo to treat victims of the country's brutal civil war. In November 2012 he was arrested and detained and in December 2013, he was found hanged in his cell.
The Syrians claimed it was suicide but questions have long surrounded the matter. Yesterday, a jury at the Royal Courts of Justice decided that he had been "deliberately and unlawfully killed" - a finding his family have always maintained.
Headline London were joined by his sister Sara and brother Afroze who talked through their reaction to the news, the role of their mother in recent months and how they felt the government handled the matter. The two also say what the kind of man Dr Khan was and what they hope his legacy will be.
