Minister: Iceland refused FBI aid over WikiLeaks investigation in 2011

Iceland's interior minister says he ordered the country's national police not to cooperate with FBI agents sent to investigate secret-busting site WikiLeaks and that it escalated into a diplomatic spat.

Ogmundur Jonasson told The Associated Press that the FBI agents were sent to the country to interview an unidentified WikiLeaks associate in August of 2011.

Jonasson's comments offered a rare glimpse into the workings of the U.S. investigation into WikiLeaks, a site which has repeatedly embarrassed Washington with spectacular releases of classified documents.

Jonasson said Friday that Icelandic officials protested the FBI trip to their American counterparts. The FBI did not immediately return an email seeking comment.
