Security tightened to protect historic Hagia Sophia

The 1,400-year-old Imperial Gate inside the Hagia Sophia Mosque has been put under protection after it was vandalized by unidentified assailants.

The unpleasant incident had come to light after a photo showing the fragmented door was uploaded by the Association of Art Historians (SATAD) on its social media platforms. "The door must be put under protection," SATAD said in the post.
