Five years have passed since Iraq liberated Mosul from ISIS in a bloody, street to street battle that left 11,000 civilians dead and much of the northern city in ruins. 

Millions fled the brutal three year rule of the terror group and hundreds of thousands more fled the deverstating fighting to recapture the city. 

But five years after victory, several neighbourhoods in Mosul still lie in ruins. 

On this week's episode, host Robert Tollast asks why is it taking so long to rebuild Mosul.
