WASHINGTON - Afghanistan has moved to the top of US Secretary of State Hillary Clintons agenda since evidence of widespread fraud emerged from last months presidential election, the State Department has said. Department spokesman Ian Kelly said Wednesday the attention was spurred by the Afghan Electoral Complaints Commissions finding of clear and convincing evidence that there was this kind of fraud on a large scale. Mrs. Clinton has been discussing concerns over voting irregularities with US officials in Washington and Kabul, Kelly told reporters. The US wants Afghan authorities to take these charges very seriously and deal with them in a way that people can have confidence in the results, he said. US officials had counted on the Aug. 20 election to yield a credible government that would be a partner in expanding military and economic-development efforts to defeat Taliban militants. The United Nations-backed complaints commission on Tuesday ordered a partial recount for polling stations that reported 100 percent turnout or where at least 95 percent of votes were cast for a single candidate. Kelly said the US ambassador to Afghanistan, Karl Eikenberry, met yesterday with President Hamid Karzai for a second time this week to discuss the need for these elections to be seen as credible and legitimate in the eyes of the Afghan people and in the eyes of the world. Were very satisfied with the way the Afghan authorities have responded to this, Kelly said, adding that Karzai himself is refraining from publicly commenting on the outcome of the election, giving a chance for the process to work out. Afghan governmental organs are also responding to allegations of complaints. Karzais rival, Abdullah Abdullah, has released photos and videos that he says show Karzais backers stuffing ballot boxes in southern Afghanistan, where violence by Taliban guerrillas kept turnout low. Kelly said that a legitimate electoral process is vital to us and vital to any kind of partnership that we would have with the government going forward. Clinton was meeting today three US senators who recently returned from a trip to Afghanistan, Pakistan and Iraq to discuss their observations and concerns. Democrats Carl Levin of Michigan, Jack Reed of Rhode Island and Ted Kaufman of Delaware are members of the Armed Services and Foreign Relations committees. Meanwhile, a UN panel annulled ballots from dozens of polling stations in Afghanistans presidential election on Thursday, kicking off a lengthy fraud investigation that could keep Afghans locked in political uncertainty for months. The August 20 election has alarmed the West whose troops are involved in an increasingly unpopular military mission. President Karzai, on course to win in a single round unless the fraud watchdog overturns the outcome, has defended the vote as honest. Preliminary results gave Karzai 54 percent of valid votes tallied this week enough to avoid a runoff with Abdullah.
