AP sources: foreign help to US could be exposed

WASHINGTON (AP) — Two Western diplomats say U.S. officials have briefed them on documents obtained by former National Security Agency contractor Edward Snowden that might expose the intelligence operations of their respective countries and their level of cooperation with the U.S.

Word of the briefings by the Office of the Director of National Intelligence comes amid questions swirling around overseas surveillance by the National Security Agency, which has angered allies on two continents and caused concern domestically over the scope of the intelligence-gathering.
