VIDEO: A window on occupied Mosul

MOSUL, Iraq - Video obtained by Rudaw media network sheds new light on life in Mosul, five months after it was occupied by Islamic State.

The film shot by an undercover reporter in Iraq's second largest city shows ISIS members mixing with ordinary people in the city. 

It shows them on the streets and moving in cars and police vehicles. 

The militants are moving freely in the city, some of them unarmed. 

The citizens look downcast but appear to pay little attention to the presence of the jihadists. 

The clip shows a shop owner and a group of people in a tea shop. But the streets are relatively empty. 

In another section of the video, an ISIS member is aiming a weapon at an unidentified target. He may be teaching two teens present how to shoot. 

Another recent video obtained by Rudaw appeared to show a decrease in the number of militants in the city and fewer of their trademark black flags
