An Arab resident of eastern Jerusalem shot seven people, including four American citizens, near Jerusalem’s Old City overnight Saturday, before turning himself in to police after an intense hours-long manhunt.

Amir Sidawi, 26, was arrested at a police station in Jerusalem after coming there of his own will with the gun he used to during the terror attack.

The previous night, Sidawi had opened fire on groups of Israelis on a bus in a parking lot near the Western Wall, injuring passengers on and off the bus as well as a pregnant woman sitting in a nearby car. The victim, 35, was evacuated to a local hospital where she underwent an emergency C-section. She and her newborn are in critical condition.

Four of the other victims were U.S. citizens, members of a Satmar Hasidic family from Brooklyn, NY, who were visiting Israel as tourists.
