An Israeli mother of four, Dafna Meir, 38, was slain by a Palestinian terrorist who Sunday entered her home in Othniel on Mt. Hebron and stabbed her to death in front of her children. The oldest girl, aged 15, summoned aid, but was too late. The killer escaped and is the object of a major manhunt. This was the first time in the current four-month long campaign of Palestinian terror that a killer has actually invaded an Israel home for murder.
