>> He was hit while appearing through a hole in the wall not 10 inches across. The Iraqi soldier, the target of an Islamic State sniper over 200 yards away. The second casualty for this unit in less than a day in the battle for Mosul. Reuters John Davison was there.

But they've been tied down by an Islamic State sniper which has just shot one of their men. He got injured, it went through close to his eye, went through his face while we were up on the roof.
So, we've come down there, they're treating him. I think
> Okay, so they've taken him off in a Humvee to the hospital to be treated. His wounds were quite serious and there was blood all over the floor. So we're just waiting now for the Hummer to come back and then we'll get out of here as well.

aqi forces saw rapid advances in Mosul's outskirts. And they say they've killed up to 1,000 militants. But holdouts like that sniper and booby traps mean it can take up to a week to clear an area even after it's been cordoned off from the rest of Islamic State's territory.
