A nearby IDF soldier shot and killed the 18-year-old, who was also from Sair.The Gush Etzion junction has been the site of many stabbing incidents since October, but it is unusual for such an attack to involve three assailants.On Thursday afternoon the IDF arrested a Palestinian man carrying a knife near Hebron’s Jewish Beit Hadassah building.In Jerusalem Thursday, police arrested an unidentified 16-year-old Palestinian male for allegedly planning to carry out a terrorist attack in the capital. According to police, the suspect was arrested at the Shuafat refugee camp checkpoint after border policemen stationed in the area saw him behaving suspiciously.“Police units surrounded the suspect and upon questioning and searching him found a knife carefully hidden on his back, inside his T-shirt,” said police spokesman Micky Rosenfeld. “He was arrested and admitted to intending to stab a security officer inside Jerusalem.”Rosenfeld said no one was injured during the arrest and that police continue to enforce heightened security in the capital to prevent future terrorist attacks.Khaled Abu Toameh, Daniel K.
