A general view shows a site producing concrete defence barriers in Kabul November 8, 2009. A kilometre-long stretch of the road is lined with family concrete barrier businesses, stacked as far as the eye can see with row upon row of freshly made, 2-metre-wide wall sections, like tombstones in a vast graveyard for giants. With security worsening and tens of thousands of American troops arriving this year, business has been brisk for concrete blast barriers. Picture taken November 8, 2009. Reuters Pictures 1 month ago
