KABUL, Afghanistan - There's still no preliminary winner in Afghanistan's presidential vote.

Election officials released just a sliver of new results Saturday, showing President Hamid Karzai with 54 per cent and challenger Abdullah Abdullah with 28 per cent.

The Independent Election Commission has now released results from 93 per cent of polling stations. Five per cent of votes have not been counted. The rest have been quarantined for fraud.

The commission had intended to release full preliminary results 10 days ago. But the process has been bogged down by fraud allegations, and officials could still be weeks away from naming a certified winner from the Aug. 20 vote.

If Karzai does not finish with more than 50 per cent, he and Abdullah will face off in a run-off.
