Despite the problems, reports continue to indicate that voter turnout has been high around the country.
Candidate Abdul Satar Sirat, speaking from his home during voting, said that "today's election is not a legitimate election. It should be stopped and we don't recognize the results." Sirat said he spoke for all the other candidates running against Karzai, although some international media have reported that 14 of the 15 challengers to presumed front-runner Karzai are challenging the proceedings.
Another candidate in the election, former Education Minister Mohammad Yunos Qanuni, said the election should be halted because of irregularities.
There were also complaints about Qanuni's supporters campaigning in Kabul's Khair Khana district in defiance of restrictions.
One man called RFE/RL's Afghan service to describe what he saw earlier today in Khair Khana: "According to election regulations, campaigning ended several days ago. But unfortunately, today Mr. Qanuni's supporters were campaigning in Khair Khana at the election centers," he said. "His team was putting up posters and cars with Qanuni's poster were driving back and forth along the roads with people talking through loudspeakers urging people to vote Qanuni. I understand this is a violation of election rules."
