Afghan election: US Senator Carl Levin makes audit call --- A senior US senator says he expects the Afghan Election Commission to conduct a "comprehensive audit" of polls cast in the presidential run-off. -- The appeal was made by the visiting Senator Carl Levin ahead of preliminary results being announced on Monday. --- The BBC's Karen Allen in Kabul says that Mr Levin's intervention appears to appease both sides in the contested presidential race. -- He called for the promises made by the election authorities behind closed doors to be translated into action. The senator said that both candidates had agreed to an audit. --- Afghanistan is under pressure to deliver a credible election in order to continue receiving foreign aid and avert a political crisis in a country where historically disputes have been fought along ethnic lines, our correspondent says. -- The election is the first time that power in Afghanistan has been democratically transferred. - More, BBC, http://www.bbc.com/news/world-asia-28182962
