A Palestinian stabbed and wounded seven people on a Tel Aviv commuter bus during the morning rush hour on Wednesday before he was shot in the leg by a security officer as he fled, police and emergency services said. It was the first Palestinian attack reported in Israel's commercial capital since a soldier was stabbed to death two months ago. Passengers on the bus said the assailant, later identified by police as a Palestinian from the occupied West Bank, stabbed the driver and then others as the vehicle slowed to a stop. As screaming passengers spilled out of the bus, prison officers in another vehicle at one of Tel Aviv's busiest intersections saw the suspected attacker trying to flee and gave chase.
