Human Rights Lawyer Calls Detention of Greenwald's Partner in the UK a 'Disgrace'

Was held for nine hours thanks to anti-terrorism legislation

(Reuters) - British authorities came under pressure on Monday to explain why anti-terrorism powers were used to detain for nine hours the partner of a journalist who has written articles about U.S. and British surveillance programs based on leaks from Edward Snowden.

Brazilian David Miranda, the partner of American journalist Glenn Greenwald, was detained on Sunday at London's Heathrow Airport where he was in transit on his way from Berlin to Rio de Janeiro. He was released without charge.
