The anxiety generated by nonstop media coverage of the wave of Palestinian violence appears to be taking its toll. Passengers on a northbound train that was traveling from Haifa on Thursday hit the emergency brakes in between stations after noticing what appeared to be a suspicious person with a knife. One of the passengers, a soldier, fired his gun into the air. There were no injuries, and no suspects were arrested. Authorities are now questioning the soldier ascertain what led him to fire his weapon.
