Pope Francis is turning his attention to Morocco's small Christian community during a two-day visit after already reaching out to the kingdom's Muslim majority and calling for a greater welcome for its growing number of migrants.

On his second and final day in Morocco, Francis is visiting a church-run social services center, meeting with Catholic priests and other Christian representatives, and celebrating a Mass on Sunday.

Morocco has become the main departure point in Africa for migrants attempting to reach Europe after Italy essentially closed its borders to asylum-seekers leaving from Libya.

Francis thanked Morocco on Saturday for protecting migrants and warned that walls won't stop people from trying to escape terrible conditions in their home countries.

He addressed migrants directly: "You are not the marginalized. You are at the center of the church's heart."
