KABUL, AFGHANISTAN - NOVEMBER 09:  An Afghan worker leans on his shovel during a break from work at the Eagle Desert Construction company concrete blast wall factory on November 09, 2009 in Kabul, Afghanistan. With security worsening in Kabul and beyond, along with thousands of American troops arriving this year, business has been thriving. While blast walls have been a common sight in Baghdad for years now, Kabul's streets have been changing steadily with the unpredictable suicide bombings and recent Taliban attack on a private international guest house on October 28 that killed five and wounded nine people. The UN has now temporarily removed 600 staff and demanded all UN personnel to move to more secure housing with a high level of security. Getty Images logo Getty Images 1 week ago
