SINGAPORE: Pope Francis left East Timor for Singapore on Wednesday for the final leg of a grueling 12-day tour of the Asia-Pacific, flying from one of the world's poorest regions to one of its richest. The marathon four-nation tour has already touched on Indonesia and Papua New Guinea, but the 87-year-old pontiff appeared in good spirits despite health concerns. A formal farewell ceremony was held at the airport in the capital Dili, where the pope's plane took off for the Southeast Asian city-state shortly after 12:25 p.m. local time (0325 GMT).
