In north-eastern Turkey, in the city of Rize, a hacker has succeeded in breaking into a sound system servicing 170 mosques. He then made alterations that replaced the call to prayer with traditional Turkish music.

The mufti of Rize has now taken measures to ensure the system´s future safety. He said few of the city´s Muslims appreciated the hacker´s action. The identity of the hacker remains unknown.

addition from b_b: found out that it was not simply "traditional" turkish music, it were songs from Zeki Müren, he died a while ago and lived his life as bisexual...might be by coincidence or as statement.
