The names were released on Tuesday afternoon of the four victims - three dual US-Israeli nationals and one British-Israeli citizen - murdered in the terror attack at a synagogue in the Jerusalem neighborhood of Har Nof.
Rabbi Aryeh Kopinsky, 43, Rabbi Avraham Shmuel Goldberg, 68, and Rabbi Calman Levine, 55, all from the Har Nof neighborhood were identified along with Rabbi Moshe Twersky, 59, as victims murdered by two Palestinian terrorists.
Kopinsky, Levine and Twersky held dual US-Israeli citizenship after making aliya from America. Goldberg, a British-Israeli national, immigrated to Israel from Britain.
Funerals for the four were to be held Tuesday afternoon.
Kopinsky's death marked a further tragedy for his family as his daughter died three years ago in sudden circumstances.
Levine leaves behind five children and nine grandchildren.
Twersky, originally from Boston, was the dean of the English-speaking Torat Moshe yeshiva and the first victim of the attack to be named.
Twersky was the elder son of renowned rabbi and author Rabbi Yitzhak (Isadore) Twersky of Boston, and a grandson of Rabbi Joseph B. Soloveitchik, one of the principle philosophers and founders of the Modern Orthodox movement.
Moshe Twersky lived in the Har Nof neighborhood close to the "Kehilat Yaakov" synagogue where the terror attack was carried out.
Eight other people were wounded in the attack, including two police officers.
According to police, the two suspected Palestinian terrorists, armed with a gun and axes, attacked worshipers after entering the "Kehilat Yaakov" synagogue on Agasi Street in the capital's Har Nof neighborhood. Two police officers quickly arrived to the scene and exchanged fire with the suspects, killing them.
Palestinian sources reported that the two suspects from the east Jerusalem neighborhood of Jabel Mukabaer were cousins.
The attack marks the latest incident in a flare of violence that has surged over the past few weeks in Jerusalem.
Israeli leaders have condemned Tuesday's deadly attack as have Palestinian Authority President Mahmoud Abbas and US Secretary of State John Kerry.
