The ongoing conflicts in Iraq are covered in tonight's episode of Frontline, titled Battle for Iraq.
Ghaith Abdul-Ahad, an Iraqi-born reporter for The Guardian, takes viewers inside Mosul as Iraqi forces try to get the city back from the control of ISIS. There is also conflict between the Iraqi Army and the Sunni population.
"As we start driving in, you realize you're not driving through a liberated neighborhood... you're driving through a battle zone," Abdul-Ahad says, noting, "This is a battle happening between two enemies on a land inhabited by civilians."
The documentary features footage of Abdul-Ahad and producer Joshua Baker surviving the likes of suicide bombings and ISIS attacking with bombs and grenades.
"I think that day, we realized the complexity of the battle," Abdul-Ahad says, of one incident. "No one knows how many civilians have been killed in this battle of Mosul, not even the government of Iraq."
Frontline's Battle for Iraq is set to air Tuesday at 10 p.m. ET/PT on PBS. The broadcast also features a special report called Hunting ISIS, in which director Olivier Sarbil follows the 1st Battalion as they try to clear ISIS out of Mosul.
"This is our country and we must protect it," says 25-year-old Anmar Alshamry, a Sunni Muslim who is part of the battalion. "Just like we took Ramadi and Fallujah back from ISIS, we'll do the same with Mosul."
