Pope Francis missed a step and fell to the ground as he was coming to an open-air altar to celebrate Mass at Poland's holiest shrine of Jasna Gora. He seemingly did not suffer any injuries. No additional information on this reported yet.

According to the Associated Press, Polish media broadcast images of the 79-year-old Argentine pontiff stumbling, then falling down out of view before being helped to his feet by altar servers.

Francis appeared to be fine as he delivered a homily and said mass for hundreds of thousands of pilgrims.

The mishap took place as the pontiff visited the revered Jasna Gora monastery in Czestochowa, southern Poland.

The pontiff arrived in Krakow, southern Poland, on Thursday to headline the World Youth Day international Catholic extravaganza.
