Racep Erdogan, Prime Minister of Turkey, responded to the recognition of Pope Francis to the Armenian Genocide by turning Hagia Sophia museum into a great mosque.
The Christian Cathedral of Hagia Sophia was turned into a mosque for 4 centuries under the Ottoman Empire, before Mustafa Kemal Ataturk, turns it into a museum for all mankind.
Mufti of Ankara, Weil Hezle, considered such recognition a new form of Crusades that should be faced by turning the church back into a great mosque.
