SINGAPORE: Pope Francis left East Timor for Singapore on Wednesday for the final leg of a 12-day Asia-Pacific tour, flying from one of the world's poorest regions to its richest. The marathon four-nation tour has already taken in Indonesia and Papua New Guinea but the 87-year-old pontiff appeared in good spirits despite fears for his health. 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).
