This is so sad :(

   [1]Greece’s Prime Minister Kyriakos Mitsotakis expressed his “sadness
   and disgust” at the vandalism to a door of Hagia Sophia in a call with
   UNESCO Director-General Audrey Azoulay, on Thursday.

   Mitsotakis said that the [2]damage to the Imperial Gate demonstrated
   disrespect for the monument’s history, integrity, and universal
   character.

   Hagia Sophia is a [3]UNESCO World Heritage site. The 15th-century door
   was used by Byzantine emperors to enter the most significant Orthodox
   place of worship.

   According to the prime minister’s office, Azoulay reiterated her
   organization’s concerns over the repercussions of the Turkish
   government’s decision in 2020 to turn Hagia Sophia, then a museum, into
   a mosque and said she will request an explanation from authorities.

   Earlier this week, the Turkish Union of Art History posted a photograph
   depicting the damage to the 15th-century door.
