Senior US military commander General Stanley McChrystal, has apologised for comments made in a magazine.
In an interview in Rolling Stones magazine, Gen McChrystal made controversial remarks critical of the Obama administration and the US military.
Gen McChrystal said he felt betrayed by the US Ambassador in Kabul over his requests for more troops.
The White House has summoned Gen McChrystal to Washington to explain 'to the Pentagon and the commander-in-chief his quotes in the piece about his colleagues.'
US military officials said Gen McChrystal would be flying from Kabul tomorrow.
The Rolling Stone article also quoted an aide describing Gen McChrystal's 'disappointment' with his initial one-on-one meeting with President Obama last year.
In a statement today, Gen Mc Chrystal said 'I extend my sincerest apology for this profile. It was a mistake reflecting poor judgment and should never have happened.'
The Rolling Stone article quoted several Gen McChrystal aides anonymously portraying a split between the US military and President Obama's advisers at an extremely sensitive moment for the Pentagon, which is fending off criticism of its strategy to turn around the nearly nine-year-old Afghan war.
The article quotes a member of Gen McChrystal's team making jokes about Vice President Joe Biden, who was seen as critical of the General's efforts to escalate the conflict and who had favoured a more limited counter-terrorism approach.
'Biden?' the aide was quoted as saying. 'Did you say: Bite me?.'
Another aide called White House National Security Adviser Jim Jones, a retired four star general, a 'clown' who was 'stuck in 1985.'
Gen McChrystal was quoted as saying he felt 'betrayed' by the leak of a classified cable from US Ambassador to Afghanistan Karl Eikenberry last year.
Gen McChrystal took command of all US and NATO forces in Afghanistan in June 2009 after his predecessor Gen David McKiernan was removed.
