9/11 ceremonies marred by reported shooting

Inaccurate media reports of a shooting by Coast Guards on Washington\'s Potomac River, today over shadowed a ceremony to remember the victims of the 9/11 attacks.



US President Barack Obama has been leading ceremonies to mark eight years since the September 11, 2001 terrorist attacks.



Speaking at the Pentagon, Mr Obama paid tribute to the victims and said time would not diminish the loss and vowed to never falter in defending the US and pursuing al-Qaeda.



The event was overshadowed after the CNN had reported that 10 rounds were fired by the Coast Guard as a vessel tried to go through a security zone, after intercepting radio messages.



The Coast Guard later said in a statement that it was an exercise, and that it would conduct a thorough review to establish how the incident could have been perceived as real.



Presidential spokesman, Robert Gibbs said that to his knowledge, the White House had not been notified of the exercise, but defended the Coast Guard\'s decision to hold it.



He criticised CNN for failing to check their reports.
