Four Israeli border policemen have been shot and wounded, two critically (UPDATE: the two died). The three Arab Muslim terrorists have been neutralized by police.
Jewish Press (h/t Liz) The three armed terrorists have been tentatively identified as Israeli-Arabs from Um El Fahm and reportedly tied to the Northern Branch of the Islamic Movement. Security forces are still checking if the IDs they were carrying are real or forgeries.
The terrorists went to the Temple Mount, and when they approached one of the gates [near the Lions Gate], they began shooting at the police. The terrorists ran into the Temple Mount and the police chased after them. They were armed with two Carl Gustav guns and a pistol.
