A British surgeon who was held prisoner in Syria for over a year has died, his sister has confirmed to ITV News.
Dr Abbas Khan's family are said to be "heartbroken" after learning of his death.
Dr Khan was arrested by the Assad regime almost a year ago after entering Syria as a humanitarian worker.
Last month, his family urged the Foreign Secretary to intervene to secure his release.
David Cameron has written to the mother of a British doctor who died in custody in Syria, describing his death as "a sickening tragedy".
The mother of British doctor Abbas Khan, who died after 13 months in a Syrian prison, has accused the regime of "murdering" her son.
