Pope Francis, battling double pneumonia in hospital for almost a month, remains stable and a recent X-ray confirmed improvements in his condition that had been seen in previous days, the Vatican said on Wednesday.

A chest X-ray confirmed improvements, the Vatican said Wednesday, just two days after doctors declared Francis is no longer in imminent danger of death.

Pope Francis continues to receive high-flow oxygen through nasal tubes during the day and a non-invasive mechanical mask at night.
