T-shirts featuring Pope Francis on sale in Colombia, ahead of the pontiff's celebration of an open-air mass in Medellin yesterday. Hundreds of thousands were expected to gather to hear the Pope speak. He was also due to visit a home for children who were victims of violence, and address priests, nuns, seminarians and their families at the La Macarena bull-ring. Pope Francis has, on this visit, urged Colombians to avoid seeking "vengeance" for the sufferings of their country's half-century civil conflict as they work towards a lasting peace.
