PICTURES FROM THE SCENE: Her name was Nadeem, or Hassan to his Israeli contemporaries.
He was a 22-year-old great-grandson of Sheikh Ahmed al-Masri, who broke bread with the son of Yasser Arafat.
But he also carried the dreams of the orphans of Yasir Arafat, the Palestinian who emerged from the remnants of the family clan, spending time in prison and radicalizing among the ranks of Fatah and the PLO.
Late Thursday, Nadeem was on a mission. His goal: to murder an Israeli soldier.
On his way, he met with three others who intended to stab Israelis. One of those men was 22-year-old Mohammad Ahmad Muhawisy of the town of Khan Yunis, whose last-minute decision to stab a soldier, causing him to disarm the attacker, averted a massacre in Jerusalem.
Nadeem was beaten to death on the spot, an act that will be treated as terrorism by Israeli police, according to authorities.
The incident ended a horrific week for the Jewish state.
On Tuesday, a Palestinian man killed a group of three in a car-ramming attack in Jerusalem. He was identified as Khader Adnan, who also stabbed an Israeli passerby, killing her in the attack.
It is unclear whether Nadeem and his alleged accomplices planned to kill in coordination with Adnan.
But the deep, violent hatred that has long fed the Israeli-Palestinian conflict is emboldened by the new rules of the game being played in the White House.
