Government forces retreated from Kunduz on Monday after the Taliban captured the provincial capital. A city of 300,000, Kunduz is a transport hub for northern Afghanistan and the biggest win for the Taliban since they were ousted in 2001. Meanwhile, concerns remain about corruption and poor recruitment in the country's NATO-trained forces as they struggle to drive the Taliban back out of the city.
