Images of Pope Francis stumbling down a step on an altar in Poland have emerged courtesy of Polish media.
The 79 year-old quickly got back to his feet as he was helped by altar servers.
He seemed not to be injured as he addressed a crowd at the Jasna Gora monastery in Czestochowa, Poland.
Security was tight at the venue following a series of attacks in Europe.
Both army and police personnel were seen to be on roads leading to the city.
