CIA Halts Spying in Europe

Spying stand-downs are common after an operation is compromised, but "never this long or this deep," said a former CIA official.

The CIA has curbed spying on friendly governments in Western Europe in response to the furor over a German caught selling secrets to the United States and the Edward Snowden revelations of classified information held by the National Security Agency, according to current and former U.S. officials.

The pause in decades of espionage, which remains partially in effect, was designed to give CIA officers time to examine whether they were being careful enough and to evaluate whether spying on allies is worth running the risk of discovery, said a U.S. official who has been briefed on the situation.
