The World Heritage Committee of the UN's cultural agency UNESCO on Friday asked Turkey to submit by early next year a report about the state of conservation of the Hagia Sophia, expressing "grave concern" over the consequences of its conversion into a mosque, AFP reports.
Turkey's move last year to convert the revered Byzantine-era Hagia Sophia cathedral from a museum into a mosque sparked fury from the international community and added to tensions with Greece.
A month later Ankara ordered another ancient Orthodox church to be converted into a mosque.
The Holy Saviour in Chora was a medieval Byzantine church decorated with 14th-century frescoes of the Last Judgement that remain treasured in the Christian world.
Both changes reflect President Recep Tayyip Erdogan's efforts to galvanise his more conservative and nationalist supporters at a time when Turkey is suffering economic woes caused by the coronavirus.
The UN body's World Heritage Committee asked Turkey to submit by Feb 1, 2022 "an updated report on the state of conservation of the property".
It said it "deeply regrets the lack of dialogue and information" over Turkey's intention to change of status of Hagia Sophia and Chora museums.
