v ages and isis. unidentified men began attacking isis. it is the first sign in what many thought might be an insurrection against isis. one sign, the troubling instant you mentioned of civilians being killed because they thought isis had left when they hadn't. we heard other instances of isis herding people from their villages towards mosul as human shields. today, the peshmerga talking about their continued advance as the iraqi kurdish forces working alongside the iraqi military. i say advance. they seem to go going through and around a lot of villages moving their front line forward quite quickly. the question is what's behind them as they go. we have seen how there are a lot of incidents when isis hide in tunnels and it seems at this point the phrase cordon off is being used.
