Afghan preliminary election results expected

26 April 2014 Last updated at 13:42 BST

Preliminary results from Afghanistan's presidential election are due to be announced, three weeks after the vote was held.

Earlier partial results put former Foreign Minister Abdullah Abdullah ahead with 43.8% of votes cast, short of the 50% needed to avoid a run-off.

The BBC's David Loyn in Kabul says there are increasing claims of fraud.

Final official results are due to be announced on 14 May after a period for adjudication of complaints.
