The top US commander in Afghanistan has been summoned to Washington in the wake of a magazine article that mocked senior Obama administration officials and diplomats. Gen Stanley McChrystal has apologised for the article in Rolling Stone. In the article, Gen McChrystal said he felt betrayed by US ambassador to Kabul Karl Eikenberry. The general's aides mock Vice-President Joe Biden and say Gen McChrystal was "disappointed" in President Obama. A spokesman for the Chairman of the Joint Chiefs of Staff Adm Mike Mullen said the admiral had spoken by telephone to Gen McChrystal to express his "deep disappointment" in the article. A White House official said Gen McChrystal had "been directed to attend [Wednesday's] monthly meeting on Afghanistan and Pakistan in person" rather than by teleconference. 'Clown' The Rolling Stone article - The Runaway General - is due out on Friday, but Gen McChrystal quickly tried to limit the damage. He said in a statement on Tuesday: "I extend my sincerest apology for this profile. "It was a mistake reflecting poor judgement and should never have happened." He adds: "Throughout my career, I have lived by the principles of personal honour and professional integrity. What is reflected in this article falls far short of that standard. "I have enormous respect and admiration for President Obama and his national security team and for the civilian leaders and troops fighting this war and I remain committed to ensuring its successful outcome." Nato spokesman James Appathurai said on Tuesday that the article was "unfortunate", but that the organisation's Secretary General Anders Fogh Rasmussen had "full confidence in General McChrystal as the Nato commander and in his strategy". The BBC's Quentin Sommerville in northern Afghanistan says the article highlights the long-suspected divisions between the US military and administration officials. One of the main targets of the article appears to be Mr Eikenberry. Gen McChrystal says he felt "betrayed" by the ambassador during the White House debate on troop requests for Afghanistan. Gen McChrystal suggests Mr Eikenberry was using a leaked internal memo that questioned the troop requests as a way to protect himself from future criticism over the deployment. The general says: "I like Karl, I've known him for years, but they'd never said anything like that to us before. "Here's one that covers his flank for the history books. Now if we fail, they can say, 'I told you so'." Gen McChrystal also appears to joke in response to a question about the vice-president. "Are you asking about Vice-President Biden?" McChrystal asks. 'Who's that?" An aide then says: "Biden? Did you say: Bite Me?"
