The Pope has been pictured in a wheelchair for the first time due to knee pain that affects his ability to walk and stand.
Francis, 85, was wheeled on stage and helped into a seat during an audience with a group of nuns and religious superiors from around the world at the Vatican.
He appears to be having a flare-up of sciatica, a nerve condition he suffers with that he's called his "troublesome guest".
The Pope has had to cancel or cut short activities several times in the last month because of pain in his right knee.
Before Thursday's event, he was able to walk the roughly 10 metres or so from the side entrance of the stage to his seat with some help.
He recently received some injections to try to relieve the pain but has continued to struggle with his mobility.
His impaired movement was apparent over Easter when he attended but did not take charge of masses at St Peter's Basilica, instead delegating a cardinal or archbishop to preside.
During a trip to Malta in April he was also pictured using an elevator platform to get on and off the plane.
