Per the Free Beacon:
Two Palestinian high school girls, cousins aged 14 and 16, from a refugee camp north of Jerusalem, skipped school Monday morning and took a tram to the Jewish side of the city. Leaving their school bags on a bench, they proceeded toward the main market place until they encountered an elderly man whom they began to stab. A policeman across the street drew his gun and called on them to drop their weapons. Instead, say police officials, the girls charged him. The policeman fired, killing one of the attackers and seriously wounding the other. Their weapons, it turned out, were pairs of scissors.
The unexpected nature of the attack, and of the attackers, has been a hallmark of the current round of Palestinian violence which began two months ago. Hardly a day passes without one or more attacks, almost all “lone-wolf” incidents involving individuals acting on their own initiative and not as part of a terror network.
