"Francis, the city prays for you." Those were the words projected onto Buenos Aires' most iconic monument, the Obelisco, over the weekend as Catholics from across Argentina flocked to churches to pray for the recovery of Pope Francis, the first Latin American pope in history. It comes as the pope, a native of Argentina, remains in critical condition Sunday with a serious lung infection in a Rome hospital, where he was admitted on February 14.

In its latest report on Francis' health condition, the Vatican reported Sunday that the pope was conscious but still receiving "high flows" of supplemental oxygen after going through a respiratory crisis and blood transfusions. His precarious health has pushed people of faith from across the world to pray for his speedy recovery.
