Documentaries on ISIL, Khmer Rouge under Venice Film Festival spotlight

At the Venice Film Festival, movie premieres and big names attract most of the attention.

But this year, crowds have also been queuing up for the documentaries on offer.

Two films focusing on the effects of the ideologies of ISIL in Iraq, and the Khmer Rouge in Cambodia have generated a lot of interest.
