Turkish Interior Minister Ali Yerli Kaya announced - yesterday evening, Sunday - the arrest of two people suspected of being the perpetrators of the armed attack. One of the suspects is from Tajikistan and the other is from Russia, suggesting that they belong to the Islamic State.
ISIS claimed responsibility for the attack through its Amaq agency, and said that the operation was carried out in response to a call from its leaders to “target Jews and Christians everywhere” About 40 people - including the Polish consul - were participating in Sunday mass when the shooting began.
