A Palestinian axe attack on an Israeli border guardsman in Jerusalem Thursday was followed by a firebomb that burned another border guard patrol jeep to a cinder. Two Israeli guards were injured. The attacks quickly escalated as Palestinians hurled rocks at the fire engines alerted to extinguish the fire. Violent Palestinian riots then erupted in the A-Tur district. The axe was wielded earlier by a 56-year old Palestinian from Hebron, a jailed terrorist freed two years ago under a prisoner exchange deal. He aimed it at the neck of the guardsman at Damascus Gate of the Old City of Jerusalem, but missed and injured him slightly in the arm. The attacker was overpowered and arrested.
