The Afghan president has admitted his office received secret payments from the US, but says the amounts were small and used legitimately.
Hamid Karzai was responding to a New York Times report that alleged the CIA sent suitcases stuffed with cash to the president's office on a regular basis.
It said tens of millions of dollars "came in secret" and cash was given on a vaster scale than previously thought.
