ALISON STEWART:

Earlier this month, the Iraqi government declared the end of combat operations in the fight against ISIS, ending three years of the militant group's violent and deadly control over one third of the nation. And as the Washington Post reports this week, the Iraqi government is now undertaking an effort to quickly bring ISIS members to justice. But just how the process is moving forward and who's being caught up in it is raising questions for an explanation. I'm joined via Skype from Ontario by Tamer El-Ghobashy, the Baghdad bureau chief for The Washington Post. I understand you've just returned from Iraq. So when you were there tell me who is being arrested? What are they being charged for? And what is the process like?
