Kerry, candidates to hold second day of meetings on disputed Afghan vote

KABUL (Reuters) - U.S. Secretary of State John Kerry held meetings late into the night on Friday in an effort to resolve Afghanistan's disputed presidential election, warning the two candidates that the country's transition to a self-reliant state hung in the balance unless the credibility of the vote was restored.

The deadlock over the vote has raised concerns about a smooth transition of power in Afghanistan, a concern for Washington as most U.S.-led forces withdraw from the country this year.
