A member of Palestinian terrorist organization Hamas opened fire in Jerusalem’s Old City, killing one and injuring three others Sunday morning.

The attack occurred near an entry point for the al Aqsa Mosque on the Temple Mount, the holiest site in Judaism, the third holiest site for Muslims, and a point of contention between Israelis and Palestinians. Fadi Abu Shkhaydam entered the area with a machine gun and fired indiscriminately in the alleyways until two female police officers fired back, with two male officers quickly assisting them, the Times of Israel reported. Two police were injured and taken to the hospital.
