ROME (AP) — Pope Francis on Saturday comforted the sister of an elderly French priest who was slain by Islamic militants in a church in Normandy as the pontiff paid tribute with a special prayer service to the courage of 20th- and 21st- century Christian martyrs. Next week Francis makes a two-trip pilgrimage to Egypt, a predominantly Muslim Arab nation where on April 9, on the Christian holy day of Palm Sunday, twin suicide bombings of Coptic churches killed 44 people. Departing from his prepared homily, Francis recounted how he was touched when last year, during a visit to a migrant detention facility in Lesbos, Greece, a Muslim father of three told him that his Christian wife had her throat slit when 'terrorists came ... and asked what our religion was.' In his homily Saturday, Francis also hailed the suffering of refugees, who are kept in detention facilities, lamenting that "international accords seem more important than human rights."
