Fort Meade officials warned drivers to follow alternate routes and "expect long delays."

This isn't the first time intruders have tried to infiltrate the NSA compound. A similar incident unfolded in March 2015, with two intruders trying to ram the gate of the compound. One was killed during that attempt, also.

The FBI tweeted that it is "aware of the incident at Fort Meade" and is sending agents to investigate.
