Pope Francis has been admitted to hospital amid speculation that he suddenly complained of “heart problems”.

Matteo Bruni of the Vatican Press Office issued a one-line statement to say that the 86-year-old Argentine Pontiff went to the Gemelli Hospital in Rome “for some previously scheduled check-ups”.

Italian media reported, however, that the Holy Father was suffering from a heart complaint and was also experiencing “breathing difficulties”.

Three newspapers also claimed that he was driven to hospital in an ambulance after he became suddenly ill following the Wednesday General Audience at the Vatican.
