Mohammed Nasser Tra'ayra, 19, from the Palestinian village of Bani Na'im, broke into Kiryat Arba today and stabbed two, leaving one wounded and one dead.

For his relatives and friends, though, it came as no surprise. Just one week ago, he praised a woman who attempted a car ramming attack on Facebook as a martyr whose "name has been exalted."

In a separate post: "Death is a right, and I want to die."

His friends report that his Facebook posts changed in March, after his cousin, Yousef Walid Tra'ayra, rammed a car into an Israeli soldier near Kiryat Arba, lightly wounding him. He carried a picture of his cousin in his wallet since.
