Displaced demonstrators from the minority Yazidi sect gather during a protest against militants of the Islamic State, formerly known as the Islamic State in Iraq and the Levant (ISIL), in Erbil, north of Baghdad on August 4. Islamic State's offensive has whipped up sectarian tensions and threatened to dismember Iraq. The sectarian conflict poses the biggest danger to the OPEC member's stability since the 2003 fall of Saddam Hussein after a US-led invasion. Reuters/Azad Lashkari
