Pope Francis' body has been moved to St Peter's Basilica, in front of crowds of worshippers.
The late pontiff lies in a simple coffin of wood and zinc, wearing a red robe with a rosary in his hands.
The Pope's coffin will remain there following the Liturgy until his funeral on Saturday.
UK correspondent Gavin Grey says crowds are coming in to pay tribute - and tens of thousands will be expected to come through in the coming days.
