The Federal Bureau of Investigation has begun questioning Libyans living in the U.S., part of an effort to identify any Libyan-backed spies or terrorists, and collect any information that might help allied military operations...A similar intelligence-gathering effort in 2003, called Operation Darkening Clouds, led to strong objections from the New York Civil Liberties Union. The organization sued in 2008 over that secret operation, calling it invasive and coercive in its questioning of Iraqi-born people in the U.S.
