Pope Francis is surrounded by security guards as he is driven away after celebrating an Easter Mass in St. Peter's Square at the the Vatican, Sunday, April 20, 2014. Cheering and applauding, the crowd tried to catch a glimpse of the pontiff as he circled around in his white popemobile at the end of the ceremony before he went to the central balcony over the basilica to deliver his commentary on the violence and poverty staining the Earth.
