New Delhi, August 1 (RHC)-- India has condemned U.S. spying on the country's ruling party as "unacceptable" after recent allegations that Washington's National Security Agency (NSA) targeted the newly-elected Bharatiya Janata Party (BJP).

Last month, The Washington Post made public a classified document, supplied by fugitive former NSA contractor Edward Snowden, which showed that the BJP was among the targets for the NSA in 2010 while it was India's main opposition. India summoned the top diplomat at the U.S. embassy in New Delhi, in response, to protest.

India also complained to the U.S. on two other occasions in 2013 over other surveillance revelations, including the disclosure that its UN mission in New York and its Washington embassy were under surveillance.

Last year, Snowden leaked two top secret U.S. government spying programs under which the NSA and the Federal Bureau of Investigation (FBI) have been eavesdropping on millions of American and European phone records and the Internet data from major Internet companies such as Facebook, Yahoo, Google, Apple, and Microsoft.

The NSA scandal took even broader dimensions when Snowden revealed information about its espionage activities targeting friendly countries. Last October, British daily The Guardian reported that the NSA had monitored the telephone conversations of 35 world leaders, many of them allies of the United States.
