LONDON (Reuters) - WikiLeaks on Sunday advised journalists not to report 140 different “false and defamatory” statements about its founder Julian Assange, who has been holed up in the Ecuadorean embassy in London since June 2012.

It was not immediately clear what prompted the advice to media organizations, but WikiLeaks singled out Britain’s Guardian newspaper for publishing what it said was a false report about Assange. The Guardian did not immediately respond late on Sunday to a Reuters request for comment.
