US Secretary of State Anthony Blinken has made a blunt new push for a UN-led peace effort in Afghanistan.
In a letter to the Afghan President Ashraf Ghani, Mr Blinken called for a 90-day reduction in violence and a transitional government formed from both sides.
Mr Blinken also said no decision had been made about whether to stick to a planned US troop withdrawal by 1 May.
He called on President Ghani to show “urgent leadership”.
A deal struck with the Taliban during the Trump administration in February 2020 committed the US to withdrawing by 1 May, but Afghan officials fear the move would create enormous security challenges.Mr Blinken warned in his letter that the Taliban could make “rapid territorial gains” across the country in a “spring offensive”.
