CIA Marks Five-Year Anniversary Of Bin Laden's Death By Live-Tweeting Mission

This is bizarre.

America's premier spy agency, the CIA, has decided to mark five years since the killing of Osama Bin Laden by 'live tweeting' details of the special forces night mission.

The al-Qaeda leader was descended upon by U.S. Special Forces in 2011 in "one of the greatest intelligence operations of all time," according to CIA director John Brennan.

The raid was the culmination of years of intelligence gathering, a "masterpiece of planning and execution" and, on Monday, the spy agency decided to relive it "as if it were happening today".

The 'live tweeting' began at 3am AEST and... well, you can read the rest:

On the fifth anniversary of the raid, the CIA's unusual move has largely been lambasted by some on social media as "grotesque" and in bad taste.

Others thought differently.

"There is nothing grotesque about celebrating a victory over the kind of terrorism that still haunts the world," one person tweeted.

Osama Bin Laden had been the most wanted man in the world since 2001, when he helped orchestrate the September 11 terror attacks on the United States.
