Afghanistan's president says there is a "window of opportunity to accelerate the peace process" following Nato's announcement that it has made no final decision on withdrawing troops.
Ashraf Ghani made the comments in an exclusive interview with the BBC.The Nato military alliance has close to 10,000 troops in the war-torn country. Under a US-Taliban deal, they were due to be withdrawn by May, after 20 years.
But there are concerns that Taliban violence could intensify.
Mr Ghani told the BBC's Lyse Doucet that Nato's announcement provided an opportunity for "all parties to the conflict to recalculate and reach a conclusion that we've long reached, that use of force is not the solution".
"We must reach a political settlement," he said.
