The Obama administration says Afghan President Hamid Karzai's accusation that the international community was responsible for the fraud in last year's presidential election is "troubling."
A White House spokesman, Robert Gibbs, told reporters Friday that Washington is seeking clarification from Mr. Karzai about his remarks.
The State Department said later that U.S. Ambassador Karl Eikenberry met with the Afghan leader on Friday to discuss the comments.
On Thursday, President Karzai told a gathering of election commission workers in Kabul that foreigners are to blame for widespread fraud during the August 20 presidential vote.
The Afghan leader singled out the head of the European Union's election observation mission, Philippe Mirollon, as well as former U.N. Deputy Chief Peter Galbraith, who was fired after a dispute with his boss on how to deal with fraud allegations.
Galbraith dismissed Mr. Karzai's charges as "preposterous." In an interview with VOA, he said the comments suggest the Afghan leader is "increasingly divorced from reality."
