LONDON -- Pope Francis on Sunday made his first public appearance since being discharged from hospital two weeks ago. Francis, 88, entered St. Peter's Square at the Vatican in a wheelchair to briefly greet crowds that were gathered to mark the Jubilee of the Sick and the World of Healthcare. The pope was wearing oxygen nasal cannulas.

The pontiff's surprise entrance came during a special Jubilee Mass for those who are sick and those who care for the sick.

After two weeks of convalescence at the Vatican, Pope Francis appeared briefly in public for the first time April 6 at the end of the closing Mass for the Jubilee of the Sick and the world of healthcare.
