Afghan elections: Abdullah says concerns 'legitimate'

More than two weeks after Afghanistan's landmark run-off to elect a successor to Hamid Karzai, electoral authorities have said they want to delay any announcement by a week due to allegations of voter fraud.

Officials say thousands of polling stations are now holding recounts where irregularities had been reported.

Abdullah Abdullah spoke to the BBC's Karen Allen about battling it out for the top job with rival Ashraf Ghani.
