First tweet reveals evidence of previously unseen sense of humour - and it has 'important insights to share'.
The Central Intelligence Agency of the US has joined Facebook and Twitter, clocking over 200,000 followers in just a few hours.
CIA's first message on Twitter was, "We can neither confirm nor deny that this is our first tweet."
The agency, which is accused by many rights organizations of spying on the social media accounts of the public, expects its new accounts to build its "online presence beyond its public website, mobile site, and official Flickr and YouTube accounts".
CIA can be followed on Twitter @CIA and on Facebook at www.facebook.com/central.intelligence.agency.
The Twitter handle had to be retrieved by a user who was impersonating the agency on the social media.
The followers of CIA on the social media will get to know its latest news, statements, and career information. The agency plans to feature artifacts and other information from the CIA's Museum as well.
A press release from the agency said that the CIA will also post updates and information from the Agency's "World Factbook," a public resource and educational tool, as well as unclassified intelligence histories and other information.
CIA director John Brennan said, "By expanding to these platforms, CIA will be able to more directly engage with the public and provide information on CIA's mission, history, and other developments.
"We have important insights to share, and we want to make sure that unclassified information about the Agency is more accessible to the American public that we serve, consistent with our national security mission."
