(Andrew Medichini | The Associated Press) Pope Francis, surrounded by shells of destroyed churches, leads a prayer for the victims of war at Hosh al-Bieaa Church Square, in Mosul, Iraq, once the de-facto capital of IS, Sunday, March 7, 2021. The long 2014-2017 war to drive IS out left ransacked homes and charred or pulverized buildings around the north of Iraq, all sites Francis visited on Sunday.
