Unidentified 'miscreants' fired shots at the Pentagon, early on Tuesday, which was rather described as a 'random event' by United States security officials, media reports claimed.
No one was reportedly injured in the shootout incident in which shots were fired into two windows at the Defense Department of Pentagon.
An official later said that initial probe has started and authorities are yet to find out whether the incident was a part of 'a larger plot.' The official added that the authorities do not have any suspects yet.
The official said that at around 0455 am EDT, sound of five to seven shots were heard near the south parking lot of the Pentagon.
Officials said it was the first incident of its kind since early March, when a gunman opened fire at a security checkpoint into the Pentagon in a point-blank attack that wounded two police officers.
The shooter, identified as John Patrick Bedell, 36, was shot by police and died hours after being admitted to a hospital in critical condition.
