Peter Erben, the head of the Joint Electoral Management Body, said at a press conference in Kabul that 50 percent of the ballots have been counted in the Farah, Nimroz, and Uruzgan provinces.
Erben also said ballots from 19 percent of all polling stations are now counted. He dismissed any concerns about widespread instances of voter fraud.
"We have some ballot boxes quarantined in, I believe, every province," he said. "This is absolutely normal. The fact that we set ballot boxes aside to be investigated is a healthy sign. It means that we're critical. We're looking at if there are any problems, and we look into these problems and decide whether there should be any consequences for the count of those boxes."
Also in Kabul, U.S. national security adviser Stephen Hadley said it will be the responsibility of the candidates to "accept the results peacefully" once the count is complete. Final certified results are due 22 October.
