Turkish officials say three people were killed Wednesday at a publishing house that printed Bibles.
They say the attackers slit the throats of the victims at the Zirve publishing house in the city of Malatya. A fourth person was injured when he jumped out of window to escape.
The publisher had received threats for printing Bibles.
Officials say police are questioning several people in relation to the attack. Turkish television showed police wrestling a man to the ground outside the building.
The attack is the latest on Turkey's small Christian minority. Last year, a Catholic priest was shot and killed in the Black Sea city of Trabzon.
