Swiss Guards line up in in St. Peter’s Square at the Vatican during the Easter Mass celebrated by Pope Benedict XVI, Sunday, April 8, 2012. Pope Benedict XVI in his Easter Sunday message has urged the Syrian regime to heed international calls to end bloodshed and commit to dialogue. After celebrating Mass in St. Peter’s Square, Benedict voiced hope that Easter’s joy would comfort Christian communities suffering because of their faith. He denounced terrorist attacks in Nigeria that have hit Christians and Muslims alike and prayed for peace in coup-struck Mali. The pope struggled with hoarseness throughout the Mass before a crowd of more than 100,000 faithful. Only hours earlier he had led a three-hour nighttime Easter vigil inside St. Peter’s Basilica.
