'Document everything. Trust no one'

When the Islamic State group seized control of Mosul in 2014, the local historian Omar Mohammed made a promise to himself and his city: document everything, trust no one. He created the anonymous blog Mosul Eye and risked his life to secretly report the daily atrocities committed by the militants. He lived next door to a senior IS commander and sometimes even went incognito as a baker, grocer or taxi driver just to get more information. It was work that could get him killed and no one knew he was Mosul Eye – not even his mother. But soon, the double life that Omar was leading began taking its toll. Would his cover get blown?
