Security fears damage Afghan economy as troops leave

Foreign troops officially end their combat mission in Afghanistan in less than a month's time.

As the deadline approaches, more than 50 countries are attending a conference in London to discuss how to boost the country's prospects after the withdrawal.

International donors are being asked to commit to new development projects - or risk seeing the country collapse.

However, security fears are already damaging the Afghan economy, reports Mike Wooldridge from Kabul.
