>> Thousands of people were detained by Islamic State and held in their notorious prisons. Now their loved ones want to know where they've gone. Since the militant group's collapse in Iraq and Syria, these are just some of the thousands of people still missing. Mezah, who now lives in Istanbul, joined forces with his brother based in Germany to start an online campaign to raise awareness about their plight.
Their other brother, Mohamad Noor, is among the missing. Arrested by Islamic State in 2013 for taking pictures, they have no idea where he is, and say no authority is doing anything to locate the detainees.>>
> Mezah, like many of the families of the disappeared, holding out hope that lost loved ones might still be alive.
They are collecting documents and we have collected a good number of documents including the names of kidnapped people and information about them. So for now we are trying to find any clue that may lead us to know their fate. What did ISIS do to them? Where did they take them?
Have they moved them to another jail or just killed them?>> Campaign members are putting pressure on the Syrian Democratic Forces who now hold Raqqa, Islamic State's former capital, so far with little success. The SDF are holding Islamic State fighters who may have important leads. According to the Syrian Network for Human Rights, over 6,000 people including over 700 children were arrested by the militants during their more than three year rule.
The rights group says IS operated at least 54 prisons at the height of their power. Over 20 in Raqqa alone, including this one in the city's National Stadium. Mezah says the most they can do is search these abandoned buildings for clues.>>
