Vatican officials announced on Sunday that Pope Francis is currently suffering from "mild renal insufficiency" amid his treatment for bilateral pneumonia.

Pope Francis slept comfortably without additional complications but remained in critical condition with kidney and respiratory issues, the Vatican said Monday morning.

Officials said Pope Francis is in critical condition as he battles pneumonia and early kidney failure. He was awake and eating normally during his treatments. Crowds have been gathering at Vatican City to pray for his recovery. Doctors reported Sunday that blood tests showed his early kidney failure was under control.
