An Icelandic media report has revealed new details about U.S. attempts to investigate the whistleblowing website WikiLeaks. WikiLeaks spokesperson Kristinn Hrafnsson told the broadcaster RUV that FBI agents landed in Reykjavik in 2011 without warning in a bid to investigate WikiLeaks operations inside Iceland. But the country’s home secretary ordered the agents to leave. Iceland then reportedly lodged a formal protest against the FBI’s action with U.S. authorities. WikiLeaks founder Julian Assange has repeatedly voiced fears he could face U.S. prosecution after the site published troves of classified material revealing U.S. abuses in Iraq and Afghanistan as well as diplomatic cables. Assange remains in the Ecuadorean embassy in London in a bid to avoid extradition to Sweden and ultimately, he says, to the United States.
