A Turkish top administrative court has ruled in favor of a proposal to turn the Hagia Sophia museum back into a mosque, CNN reported.
According to Anadolu Agency, thus, the court annulled a 1934 presidential decree converting Hagia Sophia into a museum.
The Hagia Sophia was the Roman Empire's first Christian cathedral: it was converted from a Greek Orthodox cathedral to a mosque in 1453 and then became a museum in 1935.
UNESCO has earlier warned Turkey against turning Hagia Sophia into a mosque, calling for dialogue, a UNESCO spokeswoman told AFP.
The Hagia Sophia is inscribed as a UNESCO World Heritage site.
"This inscription entails a number of commitments and legal obligations," the UNESCO spokeswoman noted.
"Thus, a state must ensure that no modification affects the exceptional universal value of the property inscribed on its territory," she said.
According to her, any modification requires prior notification to UNESCO and possibly examination by its World Heritage Committee.
