Crowds await Pope inauguration Mass

Pope Francis has inaugurated his papacy at a Mass in Rome, calling on global leaders and all the people of the world to defend the poor and the weak.

 Up to 200,000 people attended the Mass in St Peter's Square.

His homily focused on protection - of the environment, children, the elderly and those in need, who he said were "often the last we think about".

 Francis was elected by a conclave of cardinals last week to take over from Benedict XVI.
