A Catholic cardinal tipped to be the next Pope has warned that Muslims want to eradicate Christianity and to conquer Europe.
Austrian Cardinal Christoph Schönborn made the warning on Sunday during the church festival "Holy Name of Mary", which was first introduced 333 years ago in gratitude for the victory over the Ottomans in the Battle of Vienna.
According to the Archdiocese of Vienna, the cardinal said: "Will there be an Islamic conquest of Europe? Many Muslims want that and say: Europe is at the end."
He asked God to have mercy on Europe and to show mercy to its people, which he said "are in danger of forfeiting our Christian heritage".
