JERUSALEM (Reuters) - A Palestinian killed five Israelis in a Jewish settlement in the West Bank early Saturday, an Israeli military spokeswoman said. Israeli media said the attacker broke into a house in the settlement of Itamar overnight and stabbed to death a couple and three children, including a baby, from the same family. Five civilians were killed in this attack, the spokeswoman said. Troops set up roadblocks and were searching for the attacker in the area around Itamar, near the Palestinian city of Nablus.
