Since 1986, increased attacks on Jewish targets throughout Turkey impacted the security of the community, and urged many to emigrate. The Neve Shalom Synagogue in Istanbul has been attacked by Islamic militants three times. On 6 September 1986, Arab terrorists gunned down 22 Jewish worshippers and wounded 6 during "Shabbat" services at Neve Shalom. This attack was blamed on the Palestinian militant Abu Nidal. In 1992, the Lebanon-based Shi'ite Muslim group of Hezbollah carried out a bombing against the synagogue, but nobody was injured. The synagogue was hit again during the 2003 Istanbul bombings alongside the Bet Israel Synagogue, killing 20 and injuring over 300 people, both Jews and Muslims.
