Apparently this is live footage of Pope Francis performing an exorcism directly after his Sunday service in St Peter's Square at the weekend, with the internet and Italian press rampantly claiming that 'It was a prayer of liberation from evil or even a real exorcism' that he performed on a young man in a wheelchair. The Vatican are saying that he 'didn't intend to perform any exorcism. But as he often does for the sick or suffering, he simply intended to pray for someone.' so make of that what you will.
Francis is on record as having performed exorcisms in his career, and thinks that the Devil is a 'real force' that needs to be fought constantly. You may want to take a pillar of salt with this though.
