As Israelis mourned the horrific attack on a synagogue in Jerusalem Tuesday morning, many Palestinian Arabs reacted with delight. In macabre scenes played out in numerous Arab areas - including Gaza, Bethlehem and parts of Jerusalem - Palestinians took to the street to celebrate the cold-blooded murder of unarmed Jewish worshipers as they prayed in Har Nof.
Candies and other treats were handed out to children, and posters bearing the faces of the two terrorists responsible for the attack - cousins Ghassan and Uday Abu Jammal, from the Jerusalem neighborhood of Jabel Mukhaber - were waves along with PLO flags.
In one sinister ritual which played out in Gaza, dozens of young Palestinians posed with axes, knives and pistols in a tribute to the killers - who murdered four people and injured eight using knives, a meat-cleaver and a pistol, before being shot dead by police.
Even the Abu Jammal family got in the act, celebrating the "martyrdom" of their relatives - before police swooped in and arrested several of them.
