Iraqi men buy military uniforms at a shop in Basra
Iraqi men buy military uniforms at a shop in Basra, southeast of Baghdad, June 16, 2014. The United States is contemplating talks with its arch-enemy Iran to support the Iraqi government in its battle with Sunni Islamist insurgents who routed Baghdad's army and seized the north of the country in the past week. The stunning onslaught by militants from the Islamic State of Iraq and the Levant threatens to dismember Iraq and unleash all-out sectarian warfare across a crescent of the Middle East, with no regard for national borders that the fighters reject.
