UN Helpline for Civilians Fleeing Iraq's Mosul

We hear about a United Nations helpline set up for civilians who are fleeing the Iraqi city of Mosul. Plus, we speak to a Lutheran cleric who met Pope Francis, 500 years after the split between Catholics and Protestants. And, we hear more from a Nigerian official who reacts to allegations suggesting that police and security forces raped dozens of girls and women in the north-eastern part of the country.
