The head of Wikileaks claims raids on Australian journalists were linked to Julian Assange.
“The link is obvious,” Mr Hrafnsson said.
“It is the chilling effect, it is sending a signal, it’s part of the same systemic attack on investigative journalists in reporting on national security issues.”
Mr Hrafnsson’s allegation come as the US government formally submitted an extradition request to the UK for WikiLeaks founder, according to a US official, for him to face an 18-count indictment.
That indictment, which includes Espionage Act charges, was issued by the Justice Department last month and is pending in federal court in Alexandria, Virginia.
The extradition request had been expected ever since US authorities first announced a criminal case against Assange.
The 47-year-old Assange was evicted on April 11 from the Ecuadorian Embassy in London, where he had been holed up since 2012 after Ecuador granted him political asylum.
He was arrested by British police and is currently serving a 50-week sentence for jumping bail in 2012.
Sweden also seeks him for questioning about an alleged rape, which Assange has denied.
Assange was initially charged with a single computer crime violation on allegations that he worked with Manning to crack a government password. Some legal experts have said the additional Espionage Act charges might slow or complicate the extradition process to the extent the UK views them as political offences and therefore exempt from extradition.
The US official spoke on condition of anonymity because the official wasn’t authorised to speak publicly.
Manning, who spent seven years in a military prison for delivering a trove of classified information to Assange before having her sentence commuted by then-President Barack Obama, has been jailed for civil contempt in Virginia after refusing to testify before a grand jury investigating WikiLeaks.
