An Iraqi Kurdish security guard (Peshmerger) stands guard as Iraqi families fleeing violence in the northern Nineveh province gather at a Kurdish checkpoint in Aski kalak, 40 kms West of Arbil.

Islamic militants -- some with reported ties to Al Qaeda -- have taken over Iraq's second largest city, Mosul, and are making gains in other areas of the north. Ben Van Heuvelen, managing editor of the Iraq Oil Report and contributor to the Washington Post, discusses the roots of the strife and what it means for the country and the region.
