Pope Francis had quiet nights, but was still in critical condition at the Roman hospital.

Pope Francis has worked in the hospital for 11 days and a recent blood test showed early mild renal failure after a respiratory crisis. The 88-year-old pope has pneumonia in both his lungs. Nevertheless, the Vatican said he was alert and attended Mass at the church on Sunday. (AP video taken by Francesca Primavilla and Oleg Cetnic; production by Trisha Thomas)
