KABUL — President Hamid Karzai and top challenger Abdullah Abdullah both expressed confidence Friday that they had more votes than the other in Afghanistan's presidential election, one day after millions of Afghans braved dozens of militant attacks to cast ballots.
Partial preliminary results won't be made public before Tuesday, as Afghanistan and the dozens of countries with troops and aid organizations in the country wait to see who will lead the troubled nation for the next five years. The next president faces an agenda filled with crises: rising insurgent violence, rampant corruption and a huge narcotics trade.
Claims of early success by Karzai and Abdullah were an attempt to win the expectations game, and officials with the country's Independent Election Commission said it was too early for any campaign to claim itself the winner. Counting at individual polling sites has been completed, but ballots are now being sent to Kabul, election officials said.
Challenger: ‘I’m in the lead’
Abdullah's camp said it was investigating claims of fraud across southern provinces where Karzai would expect to do well.
“Indications are now that I’m in the lead and that I have won. And that I have won the elections outright and there will be no need for a run-off, but the final results are not in. But those are the indications we have at this point,” Abdullah told NBC News.
Asked directly by NBC if he was claiming victory, Abdullah replied, "No."
Though election officials previously said preliminary results would be announced Saturday, Daoud Ali Najafi, the chief electoral officer, said Friday that results won't be made public until Tuesday.
Abdullah separately told The Associated Press that government officials interfered with ballot boxes, and in some places blocked monitors from inspecting boxes or their contents.
President’s camp: ‘We think it will go our way’
Karzai's campaign said it believed the president would win enough votes for re-election, but stopped short of declaring outright victory.
“We are confident that we’ve won, but the results aren’t all in yet. But we think it will go our way,” a Karzai campaign staffer told NBC.
Karzai campaign spokesman Waheed Omar also said a second round would be "logistically, financially and also politically" problematic for the people of Afghanistan, though the election commission has said it is ready to hold a second round if needed.
"Our prediction is that the election will not go to the second round," Omar said.
A Times of London report Friday said election officials at a polling station near Kabul recorded 5,530 ballots in the first hour of voting Thursday, even though no voters were at the site when the Times' reporter arrived at 8 a.m.
Election workers said the area was pro-Karzai and was controlled by a lawmaker who said he had already voted for Karzai, even though his finger wasn't marked with indelible ink, a fraud prevention measure, the Times reported.
Observer: Vote ‘defined by violence’
The International Republican Institute, a U.S.-based nonprofit organization that had about 30 election observers in Afghanistan, said the vote was at a "lower standard" than the 2004 and 2005 Afghan elections" but that "the process so far has been credible."
Richard S. Williamson, the IRI's delegation leader in Afghanistan and a former U.S. ambassador to the United Nations, said the election "was defined by violence."
International officials have predicted that Afghanistan's second-ever direct presidential vote would be imperfect but expressed hope that Afghans would accept the outcome as legitimate — a key component of President Barack Obama's strategy for the war.
The country's chief electoral officer, Daoud Ali Najafi, said the commission had only started to receive partial results in Kabul on Friday morning.
"My advice is that all the candidates should be patient and wait until the results go through the proper channels and results are announced," Najafi said.
A U.S. Embassy spokeswoman, Fleur Cowan, said only the Independent Electoral Commission can announce official results.
"Anything else is speculation at this point," she said. "We will wait to hear from the IEC and electoral complaints commission."
Final official results weren't to be announced until early September.
American dies from wounds
As the counting continued, so did violence. A U.S. service member died Friday from wounds from an improvised explosive device in eastern Afghanistan, the NATO-led military alliance said. No other information was released. Two British troops in the south died on Thursday, officials announced.
Millions of Afghans defied threats to cast ballots, but turnout appeared weaker than the previous vote in 2004 because of violence, fear and disenchantment. At least 26 Afghans, including security forces, were killed in election-related violence. In much of the Taliban's southern strongholds, many people did not dare to vote, bolstering the hopes of Abdullah.
A top election official, Zekria Barakzai, told The Associated Press he estimated 40 percent to 50 percent of the country's 15 million registered voters cast ballots — far lower than the 70 percent who voted in the presidential election in 2004.
