I want to know the answer to the following question:
The Muslim minority is mostly located in what city?
All the background I'm provided with is that "However, many refugees who settled in former Ottoman Muslim villages in Central Macedonia and were defined as Christian Orthodox Caucasus Greeks arrived from the former Russian Transcaucasus province of Kars Oblast after it had been retroceded to Turkey but in the few years before the official population exchange.". Is that enough to answer the question?
