President Joe Biden says the September 11 attacks “cannot explain” why US forces should remain in Afghanistan 20 years later and that “it is time for American troops to come home” from the country’s longest war.

Mr Biden, in excerpts of a speech to the nation he plans later, says the US cannot continue to pour resources into an intractable war and expect different results.
