Pope Francis has shown a rare sign of anger during his trip to Mexico after an eager crowd tugged his arms and caused him to topple over onto a disabled person on a wheelchair.

Pope Francis was at a stadium in the western city of Morella on Tuesday greeting fans when he was pulled over.

The Pontiff recovered and kissed the man on the head, but did not hide his irritation.

The head of the Catholic Church yelled: 'No seas egoísta. Qué te pasó, no seas egoísta', which translates to 'Don't be selfish, don't be selfish.

Pope Francis took a couple of steps back as appeals came over the public address system asking the crowd not to clump together.
