The windows of the Hagia Sophia Mosque, which is affiliated with the federation, were broken with a beer bottle, the federation said in a statement, Anadolu Agency reported.
Highlighting the increasing incidents of hate speech and racist attacks in the country, it said the mosque was attacked for the second time since late last year.
In December 2020, a masked assailant threw rocks at windows of the mosque shortly after the evening prayers and escaped under the cover of darkness.
The statement called on security forces and the country's administration to oppose such racist attacks without discrimination and to take the necessary precautions.
"We expect security forces and politicians to take deterrent measures against such attacks,” said Gazi Cirik, chairman of the board of the Hagia Sophia Mosque Foundation.
Noting that they shared footage of the latest attack with the police, Cirik said they will feel safe as a community once the attacker is caught.
