The health of Pope Francis remains unclear as the faithful have gathered in St. Peter’s Square nightly to pray for his recovery. The 88-year-old pontiff was hospitalized almost two weeks ago, suffering from double pneumonia and mild renal insufficiency.

The Vatican has set in motion nightly prayers for Pope Francis in the hope that he might recover and get back to leading the Catholic Church.

Pope Francis, who is being treated in hospital for double pneumonia, slept well overnight and is resting, the Vatican said in a brief statement on Thursday. The 88-year-old pontiff was spending his 14th day in Rome's Gemelli hospital after coming down with a severe respiratory infection that triggered various complications.

Cardinal Baldassare Reina led the daily vigil Thursday in St. Peter’s Square to pray for Pope Francis. The pope continued to improve from double pneumonia, the Vatican said, though doctors said he needs more days of “clinical stability” before they revise their guarded prognosis.

Monday marks Pope Francis’ 10th day in the hospital, making this equal to the longest hospitalization of his papacy.

Hundreds gather to pray for Pope Francis, who is showing slight improvement in tests Thursday, according to the Vatican.

According to the Vatican, Pope Francis's condition is no longer critical. He "continues treatment and respiratory physiotherapy." A decision will soon be made whether the Holy Father will appear before the faithful during the Sunday Angelus prayer.
