It was the Taliban's worst reverse since their emergence in Spin Buldak in southern Afghanistan two-and-a-half years ago. The student militia's retreat from northern Afghanistan was as dramatic as their triumphant march beyond the Hindu Kush, which serves as a natural divide between the predominantly ethnic Pushtoons in eastern and southern Afghanistan and their Uzbek, Tajik and Turkmen countrymen living along the 2,000-km-long borders with the Central Asian republics of Tajikistan, Uzbekistan and Turkmenistan. The Taliban are believed to have lost close to a thousand of their fighters, with another couple of thousand ending up in the captivity of their allies-turned-enemies, Uzbek General Abdul Malik and his supporters.
