"Two terrorists entered the synagogue in the neighbourhood of Har Nof. They attacked with an axe, a knife and a gun. Four worshippers were killed. The police who arrived at the scene shot and killed the two terrorists," Israel Police spokesperson, Luba Samri, said.
The attackers entered the site on Harav Shimon Agassi Street, which includes a synagogue and yeshiva (rabbinical seminary), and carried out attacks in more than one location, security sources said. The wounded, including two police personnel, were taken to Shaare Zedek Medical Centre.
Netanyahu described the attack as a "cruel murder of Jews who came to pray and were killed by despicable murderers".
The Israeli Premier said the attack was the result of incitement by Hamas and Palestinian President Mahmoud Abbas, which the world had ignored.
His sentiments were echoed by Strategic Affairs Minister Yuval Steinitz who said that "the terrorists wielded axes, but the voice was that of Mahmoud Abbas."
Palestinian sources named the attackers as Rassan and Uday Abu-Jamal, relatives from the Jabel Mukaber neighbourhood of East Jerusalem.
