HERAT, Afghanistan -- Ghulam Yahya, a former mayor of this ancient city along the Silk Road, battled the Taliban for years and worked hand in hand with Western officials to rebuild the country's industrial hub.

Now, Mr. Yahya is firing rockets at the Herat airport and nearby coalition military headquarters. He has kidnapped soldiers and foreign contractors, claimed the downing of an Afghan army helicopter and planted bombs in central Herat -- including one that killed a district police chief and more than a dozen bystanders last month.
