Ex-UK PM slams US for 'imbecilic' retreat from Afghanistan

London, Aug 22 : Former British Prime Minister Tony Blair has slammed the US for an "imbecilic" decision to withdraw troops from Afghanistan in his first statement since the Taliban regained the control of the Asian country.

"The abandonment of Afghanistan and its people is tragic, dangerous, unnecessary," Blair, who took Britain into war in Afghanistan alongside the US in 2001, wrote in an article published on Saturday on the website of his Institute for Global Change, Xinhua news agency reported on Sunday.

"We didn't need to do it. We chose to do it," he said, noting that the military withdrawal was carried out "in obedience to an imbecilic political slogan" about ending "the forever wars".

"The decision to withdraw from Afghanistan in this way was driven not by a grand strategy but by politics," he said.

Blair broke his silence as chaos at the Kabul airport has worsened amid reports of stampedes and people being crushed to death.

The US has issued a security alert on Saturday, warning its citizens to avoid the Kabul airport over concerns about the potential for attacks by Afghanistan's branch of the Islamic State group.

Britain's Ministry of Defence confirmed on Sunday that seven Afghan civilians had been killed near the Kabul airport.

Blair also took a shot at the August 31 deadline set by Washington for a total withdrawal from Afghanistan.

"There must be no repetition of arbitrary deadlines. We have a moral obligation to keep at it until all those who need to be are evacuated," he said.

Leaders of the Group of Seven will meet online early next week to discuss the situation in Afghanistan, as the rift between Washington and its European allies seems to have widened over the former's hasty withdrawal from Afghanistan.
