Marwan Shweiki, a 35-year-old Israeli Arab from Jerusalem's Abu Tor neighborhood, was shot and killed Sunday on a major West Bank highway on the outskirts of Jerusalem, police and rescue officials said. The IDF determined that the shooting was a terror attack, as the gunmen fired from a hilltop above the road and had no apparent target. The terrorists opened fire on a packed van of Israeli Arabs, killing one man and wounding another two. The attackers then fled back to Ramallah. A pile of bullet casings was later found in the area. Initially, police said the cause of the late-night attack on Road 443 near the Ofer military camp was internecine clan rivalry, Jerusalem police spokesman Shmuel Ben-Ruby said. In the past, Palestinian terrorists have mistakenly attacked Arabs traveling in cars with Israeli license plates.
