LONDON (AP) — A rights group is suing Britain’s GCHQ eavesdropping agency over cyberattacks revealed by former intelligence worker Edward Snowden, saying it’s the first time the agency has been sued over hacking.

The lawsuit, filed Tuesday by Privacy International, joins a slew of legal challenges spawned by Snowden’s disclosures. Other rights groups have filed lawsuits against the agency for its mass intercept of data flooding back and forth across the world’s fiber optic cables and satellites.
