Story highlights Pope Francis calls for an end "to horror and death" in Syrian civil war

Around 60,000 gather to hear pontiff in flower-filled St. Peter's Square

Rome (CNN) Pope Francis delivered the traditional Easter Sunday Mass sermon in Rome on Sunday with a call for an end to the "horror and death" in Syria and prayed for Jesus to help world leaders end the arms trade.

"In the complex and often dramatic situations of today's world, may the Risen Lord guide the steps of all those who work for justice and peace," he told a crowd of around 60,000 people gathered in a flower-filled St. Peter's Square.

The "Urbi et Orbi" message "to the city and the world" was delivered from the central balcony of St. Peter's Basilica amid tight security with people trying to enter the square having to pass through several checkpoints.
