The United States National Security Agency's (NSA) chief has denied reports of secretively accessing communication links of Google and Yahoo Internet servers.
Army General Keith Alexander said that these companies are compelled to work with NSA and these specific requirements come from a court order, CNN reports.
Alexander further added that the NSA issues court orders to these companies in millions through the FBI, which are all against terrorism and criminal activities, and has nothing to do with the Americans.
According to the report, the operation is named “MUSCULAR”, and it is jointly operated by the NSA and its UK counterpart, the Government Communications Headquarters.
The leaked documents revealed that the NSA and the Government Communications Headquarters have been copying data flowing through fiber-optic network cables overseas, while the NSA sends millions of the records from Yahoo and Google to data warehouses at its headquarters in Fort Meade in Maryland.
The latest media revelation came after a series of allegations that arrived from leaked classified documents by the former NSA contractor, Edward Snowden.
Google and Yahoo, however, claimed that they never gave the permission to NSA or to any other government agency to access communication links to their respective servers.
