JERUSALEM, ISRAEL - 2014/11/19: Palestinian men pray inside a mourning tent for two Palestinian men who attacked a synagogue tuesday morning. Both men were killed. A day after an attack by two Palestinian men on a Jewish synagogue in Jerusalem in the neighborhood of Har Nof, which killed four Rabbis, three of whom were American citizens, and one who was a British immigrant, and one Israeli police officer, people gathered in a somber and quiet mood in front of the Kehillat Bnai Torah Yeshiva Synagogue and in the Palestinian neighbourhood of the two men who were the attackers to mourn the victims. Rabbi Moshe Twersky, Rabbi Kalman Levine, and Avraham Shmuel Goldberg, were inside the synanogue during early Tuesday prayers when Hassan Muhammad Abu Jamal and Udayy Abed Abu Jamal, two Palestinian men, entered the synagogue armed with hand guns and a meat cleaver and killed the rabbis. They also shot and wounded Israeli police officer Zidan Nahad Seif who died late Tuesday evening. This attack comes only a day after the death of a Palestinian bus driver whom Palestinians claim was hung by Israeli settlers in his bus, though Israeli authorities ruled his death as a suicide.
