The European Union (EU) Tuesday called on the Afghanistan authorities to properly investigate the “serious” allegations of fraud in presidential election.

“We note the publication of the preliminary results of the second round of the presidential election in Afghanistan and the fact that these results are subject to further audits,” Xinhua quoted an EU spokesperson as saying in a statement.

The EU has called on the Independent Election Commission to cooperate fully with the Independent Electoral Complaints Commission and the United Nations.

The electoral institutions must ensure that audits of the votes agreed by the two candidates are carried out thoroughly and transparently to ensure that the serious allegations of fraud are properly investigated and to verify that the final results reflect the will of the Afghan people,” the statement added.

Afghan presidential contender Abdullah Abdullah Tuesday rejected the preliminary results of the presidential runoff announced Monday, saying it is “illegitimate” and he doesn’t accept it.
