Israeli officials in Jerusalem are to deploy more than 10,000 police officers in a vast security operation ahead of the arrival this week of George Bush, the first US president to visit in a decade. Graffiti are being cleaned off walls, road markings are being repainted and hundreds of American flags are being put up across the city. The floodlights which illuminate the stone ramparts of the Old City will stay on for an extra two hours every night, until 2am, to give the president the chance to catch the view.
