New Delhi: Terming as “highly objectionable” the reports that said the BJP was among the parties which the US National Security Agency (NSA) was authorised to spy upon, India summoned a senior US diplomat and sought an explanation on the issue.

External affairs ministry spokesperson Syed Akbaruddin said India has clearly explained its concerns to the US government and sought an assurance that it would not happen again.

He said intrusion of privacy of individuals and institutions was highly objectionable.

According to a report in the Washington Post, India was among 193 countries “concerning” whom the NSA has been authorised to intercept information by the Foreign Intelligence Surveillance Court.

The NSA exempted only four countries – Britain, Canada, Australia and New Zealand – “in a group known collectively with the US as the Five Eyes” from such surveillance, the newspaper reported.
