"The night passed quietly, the pope is still resting," the Vatican said Thursday as there's still no update on when he will be released from hospital.

Clutching a bouquet of yellow roses, 79-year-old Carmela Vittoria Mancuso makes her way to Rome's Gemelli hospital each morning and later heads to St. Peter's Square at the Vatican in the evening to pray for the ailing Pope Francis.

Pope Francis "remained stationary" on Wednesday, "without showing any episodes of respiratory failure," but rested peacefully overnight into Thursday, the Vatican said.
