Storyville: City of Ghosts

BBC FOUR, 10.30PM

There are images of death in Matthew Heineman’s film so harrowing that it’s hard to keep watching, but these are the sights that Heineman’s subject, rebel group Raqqa Is Being Slaughtered, face daily. With their lives under constant threat, the renegade collective have made it their task to secretly film the atrocities committed by Isil in the Syrian city of Raqqa, and show the rest of the world the reality of the regime. It’s an astonishing act of citizen-led journalism, and the participants’ fear and grief, as well as their sense of purpose, are starkly captured in Heineman’s blunt and brutal chronicle of a city in turmoil.
