Pope Francis, who is battling double pneumonia in hospital, had a "tranquil" night and rested, the Vatican said on Sunday.

As Pope Francis continued his treatment at Rome’s Gemelli hospital Sunday, he expressed gratitude to medical staff while marking the approaching third anniversary of Russia’s invasion of Ukraine in a prepared Angelus message.

The Vatican announced Saturday that Pope Francis remains in critical condition at Rome’s Gemelli Hospital following a respiratory crisis that required blood transfusions.
