The discussions, some of which have taken place in Kabul, are unfolding between the inner circle of President Hamid Karzai and members of the Quetta shura, the leadership group that oversees the Taliban war effort inside Afghanistan. Afghan leaders have also held discussions with leaders of the Haqqani network, considered to be one of the most hard-line guerrilla factions fighting here; and members of the Peshawar shura, whose fighters are based in eastern Afghanistan.
