Pakistan boycotts global conference on Afghanistan's future

Afghan President Hamid Karzai has said international support after foreign forces withdraw in 2014 is crucial if Afghanistan is to remain stable.

His comments opened a major global conference on Afghanistan's future in the German city of Bonn.

It comes 10 years after a similar gathering held in the city, weeks after the Taliban fell from power.

But key player Pakistan is boycotting this round in protest at a Nato attack on a border checkpoint last month.

The BBC's world affairs correspondent David Loyn reports.
