LONDON (AP) — The British government fears that material seized from the partner of a Guardian journalist could compromise counterterror operations, a senior national security adviser said Friday, arguing that intelligence agents in the field could be exposed as a result of the data.
It was the first time the government has offered specific reasons why security services and police are so concerned about material seized from David Miranda — the partner of Guardian journalist Glenn Greenwald.
Miranda was detained at Heathrow Airport and questioned for nearly nine hours under terrorism legislation earlier this month, but the government had earlier said only that it required access to the files on national security grounds.
Greenwald has written stories based on material leaked by former U.S. National Security Agency contractor Edward Snowden. Full story for BostonGlobe.com subscribers.
