The US will insist that the Taliban and insurgent groups break ties with al-Qaeda, end violence and accept the Afghan constitution which includes protection for women and minorities.
Official peace talks on Afghanistan between the United States and the Taliban were delayed today, amid a row about an office.
American negotiators will sit down with black turbaned men from the Taliban, at least one of whom speaks impeccable English.
