City of Ghosts is a film that really understands how the problem started.
The documentary by a group of journalists called RSBS (Raqqa Is Being Slaughtered Silently) uses the smartphone as a weapon to fight terrorism.
It’s more graphic and depressing than anything in the news.
Raqqa should have been freed but it is still has major problem there.
It may also be worth watching this alongside the one produced by NHK.
