US Secretary of State Mike Pompeo on Monday slashed aid to Afghanistan's government after a mission to Kabul failed to bridge a divide between feuding leaders as he moved forward with the Taliban on a deal to pull troops.

Pompeo made the surprise trip in hopes of reviving a landmark US accord with the Taliban to end America's longest war and, stopping in Qatar on his way back, became the highest-ranking US official ever to meet the Islamist insurgents. In stark criticism of a government-backed for nearly two decades by the United States, Pompeo voiced disappointment that President Ashraf Ghani and his rival Abdullah Abdullah could not bridge their differences when he met them in Kabul.
