AKIPRESS.COM - US Secretary of State John Kerry has arrived in Afghanistan to try to help resolve tensions over the country's disputed presidential elections.

He will meet both of the candidates claiming victory in June's run-off, Abdullah Abdullah and Ashraf Ghani.

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

President Hamid Karzai is stepping down after more than 10 years in power after the US-led overthrow of the Taliban.

The fact Mr Kerry made this trip at such short notice, is an indication of just how concerned the US is about the risk of Afghanistan descending into post-election turmoil, the BBC's Aleem Maqbool in Washington reports.
