Afghanistan peace talks stall over planned prisoner exchange

US agreement with Taliban was intended to help Afghans reach deal on political future

Afghanistan's political chaos has deepened with disputes over presidential election results and a planned prisoner exchange delaying peace talks with the Taliban even as the US starts its troop withdrawal.

A US agreement with the Taliban signed last month on the departure of American forces was meant to set the stage for Afghans to reach a deal on their country's political future after decades of civil war but those talks, expected to begin this week in Oslo, have been postponed indefinitely.
