After a decade of unfathomable violence and human tragedy that has made Syria the defining war of the early 21st century, the fighting has tapered off but the suffering hasn't.

At least eight migrants and guards were killed, and scores more injured, in a fire on Sunday at a holding facility in Yemen's capital, the International Organization for Migration said. 

Pope Francis vowed Sunday to keep Iraq in his heart, as he concluded the largest mass and final public event of a historic trip meant to encourage the country's dwindling Christian community and deepen interfaith dialogue.

Pope Francis and Iraq's top Shiite cleric delivered a powerful message of peaceful coexistence Saturday, urging Muslims in the war-weary Arab nation to embrace Iraq's long-beleaguered Christian minority during an historic meeting in the holy city of Najaf.

Grand Ayatollah Ali al-Sistani said religious authorities have a role in protecting Iraq's Christians, and that they should live in peace and enjoy the same rights as other Iraqis. The Vatican said Francis thanked al-Sistani for having "raised his voice in defense of the weakest and most persecuted" during some of the most violent times in Iraq's recent history.
