“We are disappointed with the decision of the Turkish government to change the status of Hagia Sophia,” RIA Novosti quoted her as saying.

According to Ortagus, the building is an important part of the "historical sites of Istanbul." Ortagus recalled that Hagia Sophia is a UNESCO World Heritage Site.

The representative of the State Department added that the Turkish authorities pledged to maintain access to this facility for all visitors.

“We look forward to hearing his plans for the future management of Hagia Sophia to ensure its unhindered access for everyone,” said Ortagus.

On July 10, the Turkish State Council overturned the 1934 decision to turn Hagia Sophia (Hagia Sophia) in Istanbul into a museum.

Then Turkish President Recep Tayyip Erdogan signed a decree that allowed Muslim worship to be held in Hagia Sophia.
