Election investigation urged in AfghanistanListen /
The investigation of ballots from more than 7,000 polling stations in Afghanistan has been urged by the UN mission in the country, UNAMA.
It follows the publication of initial results of elections which are being challenged by presidential contender, Abdullah Abdullah.
Mr Abdullah, who has repeated claims that the election process was fraudulent, faced Ashraf Ghani in a run-off vote which took place in June.
The preliminary results show Mr Ghani has won the vote.
UNAMA has urged the Afghan election institutions to conduct additional audits of ballots from more than 7,000 polling stations in what it called "a rigorous, timely and expeditious manner."
The mission reiterated its call for the candidates to exercise restraint and to ensure their supporters do not act in a way that could lead to civil disorder and instability.
