From the New York Times and the team that brought you the daily, this is Caliphate.

We're going to be doing a police station in western Mosul.

This is the place where police officers and members of the Iraqi Security Force are bringing ISIS members who were captured during the battle for western Mosul.

We're hoping to interview some of the detainees.

We're here.

Chapter 9. Prisoners. Part 1.

So this is the police station. Let's start at the jail.

So we drive up to a building. They appear to have taken over a state-led building in western Mosul.

Most likely a municipal building belonging to the Iraqi government. Perhaps it was the state-led home of a wealthy person.

The coils of barbed wire on the outside. It was half the guard.

And sandbags all around the building on the balcony.

It's only me, you and Andy are going in. No security details.

You, me and Hawk, walk in.

We are currently in a Iraqi prison where rooms are full of different ISIS members.

And basically, breathing through my mouth right now.

The first thing that hit me was the smell. The smell of sweat, the smell of dirt.

And we began passing these metal doors with big latches on them.

There's like a great window in some of the doors.

And remember, when we passed one, you could see these faces peering out at you.

We're moving very good.

We're taking upstairs. And the security officials who run this prison took us into one of their commander's offices.

And this is the main facility where ISIS prisoners are transferred.
