The Neve Shalom Synagogue in Istanbul has been attacked three times . First on 6 September 1986 , Arab terrorists gunned down 22 Jewish worshippers and wounded 6 during '' Shabbat '' services at Neve Shalom . This attacked was blamed on the Palestinian militant Abu Nidal . The Synagogue was hit again during the 2003 Istanbul bombings alongside the Beth Israel Synagogue , killing 20 and injuring over 300 people , both Jews and Muslims alike . Even though a local Turkish militant group , the Great Eastern Islamic Raiders ' Front , claimed responsibility for the attacks , police claimed the bombings were " too sophisticated to have been carried out by that group " , with a senior Israeli government source saying : " the attack must have been at least coordinated with international terror organizations "
