Israel has ordered preparations for a complete closure of the West Bank after a shooting near Hebron left at least five people wounded. Two armed Palestinians opened fire in the area, according to the Israeli account of what happened. A total closure would seal crossings and sharply restrict Palestinian movement between towns and into Israel. The timing carries weight, since parliamentary elections are only four days away and security sits close to the center of the vote. Every measure announced this near to a ballot tends to be read through a political lens as parties stake out their positions. Tension on the ground had already been running high, and the incident looks set to push it further before polling day.
