The Taliban has defeated, co-opted or sent Afghan security forces fleeing from wide swaths of the country, even though they had some air support from the U.S. military. Taliban negotiators headed to the presidential palace Sunday to discuss the transfer, said an Afghan official who spoke on condition of anonymity for fear of reprisals. At Kabul International Airport, Afghan forces abandoned the field to Western militaries, said a pilot who spoke on condition of anonymity to discuss security matters. The militants also took Maidan Shar, the capital of Maidan Wardak, on Sunday, Afghan lawmaker Hamida Akbari and the Taliban said. Later, Afghan forces at Bagram air base, home to a prison housing 5,000 inmates, surrendered to the Taliban, according to Bagram district chief Darwaish Raufi.
