Pope Francis spent another night without incident, the Vatican said on Friday, marking a week in the hospital for the 88-year-old pontiff suffering from pneumonia in both lungs. "The night went well, this morning Pope Francis got up and had breakfast," the Vatican said in a regular morning update.

It was the latest in a series of incrementally positive updates in recent days from the Vatican, which has regularly been publishing information -- however modest -- about the Argentine pope's state of health.

Francis was admitted to Rome's Gemelli hospital last Friday with bronchitis, but it later developed into pneumonia in both lungs, sparking widespread alarm.

But the Vatican said Thursday he continued to not have a fever and his "hemodynamic (blood flow) parameters continue to be stable".
