A Palestinian militant was killed Friday when an explosion went off in a van he was driving in a West Bank (searchrefugee camp, witnesses said.

The militant was identified as Ahmed al-Abed from the Al Aqsa Martyrs' Brigade (search), an armed group with ties to Yasser Arafat's Fatah movement.

A member of Al Aqsa told The Associated Press that al-Abed's car was apparently hit by an Israeli tank shell fired from a mountaintop post overlooking Balata.

The army had no immediate comment.
