When the Islamic State group took over Mosul in Iraq in 2014 they flooded the internet with propaganda, claiming life under IS was fantastic. One historian living in the city decided to post a counter-narrative online. Omar Mohammed set up "Mosul Eye" to expose the atrocities and failings of IS fighters, but it was at great risk to his own safety. Omar tells Rebecca Kesby how he posted news from Mosul to the outside world from right under the noses of the Islamic State group. He says he felt it was his duty to tell the real story.
