Perhaps, her town is majority Bosniak but identity in whole sandzak region is confusing. There are Muslim Serbs, Bosniaks, people who identify just as Muslims as national identity.
The region has given many athletes-
Murat Yenipazar has roots in the same town, Kalac and Eda are also said to have roots from theres.
Emina Jahovic (Sandal), her brother Turkcan who represented Turkey in basketball, many Serbian representatives in athletics- Bibic, Kolasinac, Sinancevic (all Muslims). Many football players, 2nd best Serbian tennis player after Djokovic today- Hamad Medjedovic.
I wanted to give examples cause I saw there was big fuss on social media after Hena said that she comes from a Muslim family with people. To the point where people were confused that she doesn’t wear hijab lmao, and talks about representing Serbia when she has possible Bosniak roots.
The 90s war didn’t affect Sandzak region so it’s still very much multicultural and peaceful. Muslims from the region are kinda more connected with Belgrade and Turkey then with Bosnia which is kinda strange. Religion is much bigger part of the identity there then national.
