Pope Francis lands in Singapore for final stop on 12-day Asia-Pacific tour
The 87-year-old pontiff has defied doubts about his health during a journey that has taken him from a Jakarta grand mosque to a remote jungle of Papua New Guinea.
In recent years, the ailing pope has undergone hernia surgery and has been plagued by respiratory issues. He now relies on a wheelchair, walking sticks or aides to get around.
But throughout the trip, he has carried out dozens of public engagements, energised congregations through impromptu call-and-response and repeatedly sat for hours in the brutal tropical heat.
