NEW YORK - Rising complaints about Afghanistans elections are causing concern among Western officials, who say they may put the legitimacy of the polls into question, according to The New York Times. Citing one instance in a dispatch published in Mondays edition, the newspaper reported a Kabul teacher assigned to a polling station was taken away by a local chieftains men when he protested after finding ballot boxes already full on Election Day. Since then, he has been receiving threats while his polling station is being investigated. The Times report quoted Afghan election officials saying Sunday that serious fraud reports had suddenly doubled to 550 from 270 out of more than 2,000 total complaints. This has raised concerns about likely public outrage and delay in making the final official results public. Western officials say they fear the country may be faced with a national government in limbo amid an expanded NATO war against the Taliban. It does indicate there were a lot of allegations that have to be taken seriously, and if fraud did take place, that it was systematic, Martine van Bijlert, an analyst with the independence policy research group of Afghanistan Analysts Network, told The Times. Election observers and analysts told the Times the Aug. 20 elections had surpassed previous ones in the scale of bribery, corruption of election officials, ballot stuffing and altering the count. President Hamid Karzai, who is seeking re-election, and his leading rival, former Foreign Minister, Abdullah Abdullah, both say they are winning. With results of about a third of the votes announced, Karzai was leading with 46 percent, but he needs to get more than 50 percent to avoid a runoff.
