If I'm reading Wikipedia properly, at the moment that is just AEK Larnaka FC (Cyprus), Hapoel Ironi Kiryat Shmona Football Club (Israel), İstanbul Başakşehir F.K (Turkey), SA 2013 Târgu Mureș (Romania) and SC Rheindorf Altach (Austria) ??
Got that from here: https://en.wikipedia.org/wiki/2015%E2%80%9316_UEFA_Europa_League#Third_qualifying_round
