UN Secretary General Ban Ki-moon says recent remarks by Afghan President Hamid Karzai are troubling and unhelpful.
Karzai alleged in a public forum last week that the UN and the international community interfered in last year's Afghan elections.
He also reportedly has threatened to join the insurgents unless the US and its allies ease up on pressure to reform. His spokesman has since denied the reports.
Ban Ki-moon told reporters today he is "troubled by all this rhetoric," saying it is neither helpful nor desirable.
Ban said the international community expects harmonious and full cooperation from the Afghan government.
