Greenwald To Publish More Snowden Revelations in Wake of Partner's Detention in the UK

David Miranda was detained for nine hours at Heathrow airport

(Reuters)—The journalist who first published secrets leaked by fugitive former U.S. intelligence agency contractor Edward Snowden vowed on Monday to publish more documents and said Britain will be "sorry" for detaining his partner for nine hours.

British authorities used anti-terrorism laws on Sunday to detain David Miranda, partner of U.S. journalist Glenn Greenwald, as he passed through London's Heathrow airport.
