Conflicting reports about the explosion that critically injured a Fatah activist near Tul Karem this morning. Ashraf Elbardawil was on a northern Shomron road when his car exploded. Israeli sources originally said they knew nothing of the incident, but later said it was likely due to a \"work accident\" caused when the bomb the victim was preparing exploded pre-maturely. Palestinian sources said the explosion was caused by an Israeli liquidation attempt.
