The Argentinian pope is entering his fourth week of convalescence during which doctors have advised him to avoid crowds.

A convalescing Pope Francis has greeted the crowd in St_ Peter’s Square on Palm Sunday, wishing more than 20,000 faithful a “Good Palm Sunday, a good Holy Week."

Pope Francis made his first public appearance since being discharged from hospital two weeks ago after treatment for double pneumonia, entering St. Peter's Square at the Vatican in a wheelchair on Sunday to greet cheering crowds.
