Palestinian children stand to form Pablo Picasso's Dove of Peace as part of a project by British aerial artist John Quigley and the United Nations Relief Works Agency (UNRWA), at the foot of the Mount of Temptation in the West Bank city of Jericho November 25, 2011. It took some 1000 children from United Nations schools to create the project produced as part of the "Peace on Earth" project, a global musical prayer for peace which will be broadcast globally from Bethlehem's Manger Square on Christmas day, a U.N. press release said.
