TV show gives glimpse into Mosul

Civilians in besieged city take to the airwaves to describe life and 'inhumane treatment' under IS

As evening approaches in Iraq's northern city of Irbil, TV presenter Bakr Mahmoud Mahdi prepares to go live with a show called Freedom Studio.

His callers - and there have been fewer of them lately - are civilians living inside the city of Mosul, Iraq's second-largest, and describing what life is like under the rule of the Islamic State group.
