The CIA posted “live tweets” on Sunday about its mission to kill Al-Qaeda supremo Osama Bin Laden to mark his fifth death anniversary. The tweets were posted in a manner as if it were happening at present. The move was highly criticised by the internet users, with some even claiming it as “grotesque” and “embarrassing.”

“To mark the 5th anniversary of the Usama Bin Laden operation in Abbottabad we will tweet the raid as if it were happening today,” the CIA tweeted.

The operation in 2011 that eventually led to the capture and killing of Bin Laden following a decade-long manhunt was described as “one of the greatest intelligence operations of all times” by CIA Director John Brennan. The US Special Operation Forces attacked the 9/11 mastermind at his hideout in the Pakistani garrison town of Abbottabad.

“The raid was a masterpiece of planning and execution,” Brennan had said in a statement.

The live tweets revealed details of the operation that also killed three other men and a woman. Bin Laden’s son was also killed in the operation. The spy agency started tweeting the events as it happened from 3 a.m. AEST. But the move did not go down well with the netizens. One internet user even tweeted, “you are celebrating killing the monster of your own creation.”

Some users even questioned the ethics of celebrating an operation that led to killings. The agency carried on with its tweets despite the criticisms, the Sydney Morning Herald reported.

“1:51 pm EDT – Helicopters depart from Afghanistan for compound in Abbottabad, Pakistan,” read one of the Tweets.

The ABC reported that this isn’t the first time that the operations have been live tweeted. At the time of the real incidents, an IT professional in Abbottabad posted live tweets unknowingly on what’s happening.

The announcement of Bin Laden’s death by US President Barack Obama prompted 4,000 tweets per second.
