ROME (AP) — The Vatican on Sunday released the first photograph of Pope Francis in more than a month, showing the pontiff in a three-quarter view from behind wearing a purple stole typical of Lenten liturgical vestments and sitting in a wheelchair before the altar of his personal hospital chapel.

The pope was admitted to Rome's Gemelli hospital on Feb. 14 with a severe respiratory infection that has required evolving treatment.

The photo is said to have been taken Sunday when Francis was co-celebrating Mass in the chapel of his hospital suite where he has been battling a health crisis.
