The Israel Defense Forces overnight Sunday began preparations to demolish the homes of two Palestinian men suspected of stabbing to death 18-year-old Israeli Dvir Sorek last week near the West Bank settlement of Migdal Oz. The military said its troops measured the homes in the Palestinian village of Beit Kahil in the southern West Bank so that engineers can plan the best ways to demolish the structures. No date has yet been set for the demolition. Sorek’s body was found early Thursday morning on a road leading to the religious seminary where he was studying in Migdal Oz as part of a program combining military service with Jewish study known as hesder.
