From the Guardian:
Four Israelis were killed and eight more wounded in a frenzied assault by two Palestinian men on Jewish worshippers praying at a Jerusalem synagogue in the most lethal incident in the city in years.
The two assailants who launched their attack with meat cleavers and a gun during early morning prayers were then killed by police officers in the ensuing gun battle at the scene of the attack.
The deaths occurred as the two men – identified by family members as cousins Ghassan and Uday Abu Jamal from the East Jerusalem district of Jabal Mukaber – burst into the Bnei Torah synagogue in Har Nof, an ultra-Orthodox Jewish neighbourhood of West Jerusalem.
Three of the victims held dual US-Israeli citizenship, and one was a British-Israeli citizen – 68-year-old Avraham Shmuel Goldberg, who emigrated to Israel from the UK in 1993.
The three US citizens were 59-year-old Rabbi Moshe Twersky – the head of an English speaking religious college – Aryeh Kopinsky, 43, and Kalman Zeev Levine, 55. The grandson of one of the founders of the Modern Orthodox movement, Twersky lived close to the scene of the attack in Har Nof.
