The U. S. State Department says at least 150 of its embassies around the world do not meet America's security standards. Sarah Morris reports from Washington. The United States State Department has spent 4 billion dollars on measures to protect buildings and staff at its foreign embassies and consulates over the last decade. Despite this, it's now estimated that at least 150 U. S. missions abroad have not attained designated safety standards according to documents obtained by the AP News Agency. The move to improve security was spurred by the attacks on the American embassies in Kenya and Tanzania a decade ago, in which 231 people were killed. A slump in vehicle sales by the three big U. S. car manufacturers has renewed worries about the American economy. General Motors posted an 18% drop in sales in June, Ford unveiled a 29% slump, Chrysler's sales were down by 36%. Mark Gregory reports. The combination of record fuel prices and an economy close to recession has led to a slump in sales. On current trends, fewer than 14 million cars and light trucks will be sold in the U. S. this year, the market's worst performance in 15 years. Shares in General Motors, America's biggest car maker, have fallen to a level last seen in the 1950s.
