The 76-year-old's well-being is under close scrutiny because of the shock February resignation of his predecessor Benedict, who said his health was declining and a stronger man could do the job better. 

A Vatican spokesman said Francis had cancelled several meetings with cardinals and bishops on Friday morning, but would still take part in the ordination of a bishop in the afternoon. 

"There is no reason for worry," Father Federico Lombardi said.
