Greece’s foreign ministry issued a terse statement on Tuesday afternoon saying it was “appalled and saddened by the images of the vandalism against the Imperial Gate of the Hagia Sophia – a World Heritage Site – in Istanbul.”

The statement came after images emerged showing the vandalism.

“…We call on the competent authorities to do their due diligence in order for those responsible to be brought to justice and the damage to the Monument to be immediately repaired,” it added.
