Afghan poll crisis: John Kerry to meet with candidates

US Secretary of State John Kerry has arrived in Afghanistan to try to resolve tensions over the country's disputed presidential election, which are threatening to destabilise the country.

He will meet the candidates, Abdullah Abdullah and Ashraf Ghani, who are both claiming victory following the run-off vote in June.

Mr Kerry earlier warned against a power grab, amid reports that Mr Abdullah was planning a "parallel government".
