An Afghan police spokesman says unknown gunmen have kidnapped two Turkish nationals in western Afghanistan. Spokesman Rauf Ahmadi says authorities found the Turks' abandoned car along with their passports west of Herat city, near the border with Iran. He says the two men worked for a road construction company in the area. They disappeared on Monday. There have been a number of kidnappings in Herat province in recent months, mainly targeting Afghans. Most of the kidnap cases there are of a criminal nature and not linked to the Taliban insurgency.
