I managed to find these two exchanges[1][2]. Both allow buying and selling using your bank account and from a quick search, it looks like they are both reputable but you may want to ask more about them.

Alternatively, you could trade with Turkish people through LocalBitcoins or link your Bank account to Skrill and exchange your BTC to Skrill so you can withdraw.
