Israeli police say a man killed by a Palestinian attacker in a stabbing spree in the port city of Jaffa was an American tourist.
Officials say 28-year-old Taylor Force was a graduate student of Vanderbilt University and was visiting Israel on a school trip.
The attack was just one in multiple Palestinian stabbing and shooting attacks that came as Vice President Joe Biden arrived in Israel on a two-day visit as part of a regional tour of the Mideast.
Four Palestinian attackers were shot and killed Tuesday in a rash of violence that wounded a dozen Israelis. It was the latest bloodshed in a five-month wave of near-daily Palestinian attacks on civilians and security forces.
