Former UK Prime Minister Tony Blair has described the US withdrawal from Afghanistan as "tragic, dangerous, and unnecessary" in his first statement since the fall of Kabul to the Taliban.
He said the decision was made "in obedience to an imbecilic slogan about ending 'the forever wars'".
Mr Blair led the UK when it invaded the country alongside the US in 2001, following the 11 September attacks.
He said the exit of allied troops would have Jihadist groups "cheering".
Mr Blair also said that Britain has a "moral obligation" to stay in Afghanistan until "all those who need to be are evacuated".
