Marking Christianity’s most hopeful day, Pope Francis made an Easter Sunday plea for peace and dialogue in Ukraine and Syria, for an end to terrorist attacks against Christians in Nigeria and for more attention to the hungry and neediest close to home.

Well over 150,000 tourists — Romans and pilgrims, young and old — turned out for the Mass that Francis celebrated at an altar set up under a canopy on the steps of St. Peter’s Basilica.

Francis noted that this year the Catholic church’s celebration of Easter coincided with that of Orthodox churches, which have many followers in Ukraine.

Francis prayed that God would “enlighten and inspire the initiatives that promote peace in Ukraine, so that all those involved, with the support of the international community, will make every effort to prevent violence.”

In eastern Ukraine, the holiday was marred by a deadly shooting Sunday fueled by tensions between pro-Russian supporters in the east and those loyal to an interim government in Kiev. The clash appeared to defy an international agreement reached last week in hopes of ending months of unrest.
