When Pope Francis becomes the first pontiff to visit an independent East Timor, he will confront a clergy beset by child abuse scandals that have been largely ignored by the deeply Catholic country's freedom heroes.

Cases include Nobel-winning Bishop Carlos Ximenes Belo, who helped Asia's youngest nation free itself from Indonesian occupation, but who the Vatican secretly punished over claims he had sexually abused young children for decades.

There are calls for the 87-year-old pontiff to speak out on child abuse when he lands in the former Portuguese colony Monday as part of his Asia-Pacific tour. "We ask Your Holiness to encourage the leaders and the people of Timor-Leste to take more effective measures to prevent sexual abuse," the Timor-Leste NGO Forum, a civil society coalition, wrote in a letter Wednesday to Francis.
