Sectarian Divide Clouds Fight For Tikrit

The United Nations is sending aid for Iraqi civilians they fear have been displaced, as government forces continue their offensive aimed at driving the Islamic State group out of the city of Tikrit.

Progress has been slowed by roadside bombs and booby traps planted by the militants. There is also concern about the battle turning sectarian. Shiite militias backed by Iran are fighting against ISIS, a mainly Sunni group.

Mitchell Prothero, Iraq bureau chief for McClatchy Newspapers, tells Here & Now's Robin Young that "to be a Sunni in Iraq who doesn't support ISIS right now is a very dangerous place to be."
