A Taliban official has rejected the idea that the US could retake a key airbase in Afghanistan after President Donald Trump told reporters he wanted it back.

A British couple who were detained for nearly eight months by the Taliban in Afghanistan have been released, an official with knowledge of the case has said. Peter Reynolds, 80, and his wife Barbie, 76, who have lived in the country for nearly two decades, were held after being stopped while travelling home on 1 February.
