Explosions at two synagogues in Istanbul have killed 23 people and wounded more than 80 others. The first blast rocked the Neve Shalom synagogue, in the central Sisli district of the city on Saturday morning. ''It was a huge bang, my windows are full of debris. It shook my stomach," said one eyewitness. Details of the explosion at the Beth Israel synagogue nearby are still emerging. Turkish television has been showing pictures of injured people being carried away from the blast on stretchers. Rescue workers say the death toll is likely to rise. Turkish television says many of the injured have inhaled ammonia and are being treated by doctors. Police and local residents say a car laden with explosives caused the blast. The attacker is believed to have died in the explosion. A Turkish group called the Great Eastern Islamic Raiders Front has claimed responsibility for the car bombing. The Neve Shalom synagogue was the scene of an attack by a Palestinian gunman in 1986. Twenty-two Jewish worshippers were killed. A bomb attack on the same temple followed in 1992. No one was killed in the attack, claimed by Lebanese group Hizbullah.
