The inauguration Mass for Pope Francis has been held in St Peter's Square in Rome, marking the official start of his papacy.

Francis earlier toured the square in an open-topped vehicle, descending to bless pilgrims behind the barriers.

His homily called on global leaders and all people of the world to protect the weak and the poor.
