The Washington Post reports the National Security Agency is recording every single phone call from one unnamed country. A program called MYSTIC tapes the calls, and a tool called RETRO allows the NSA to access the recordings for up to 30 days. The Post attributes the information to unnamed sources in positions to know about the program, and to documents given to the paper by former NSA contractor Edward Snowden.

The newspaper obtained a classified summary of the MYSTIC program, and is withholding the name of the country at the request of the White House. The Post also says the current secret intelligence budget names five other targets of the RETRO tool. The NSA launched the program in 2009 and reached 100% recording of the unknown country’s phone network in 2011.
