In Afghanistan, three more regional capitals fell to the Taliban yesterday. That makes nine in less than a week. One of the latest to fall is the city of Pul-i-Khumri, in Baghlan province, a vital piece of territory that Chris Woolf knows well. He came under fire there as a BBC reporter back in 1991. Host Marco Werman speaks with Wolff, a former staffer with The World and the author of a forthcoming book called, “Bumbling Through the Hindu Kush.”
