Two of the victims -- all of whom had their hands and feet tied -- were found dead in the offices of a publishing house that printed books on Christianity. The third died in hospital. Two of the deceased were reportedly employees of the publishing house.
"One of them is highly likely to be a German, the other is believed to be a Turk. The third is also likely to be a Turk, but we still have doubts," the Governor of the eastern city of Matalya, Halil Ibrahim Dasoz, told the NTV news channel.
An aide to the governor told AFP that the Zirve publishing house "was engaged in missionary activities."
