The FBI is investigating several suspicious packages that were delivered to military and intelligence locations in the Washington, D.C., area, U.S. officials told CNN on Monday.
One official said more than 10 devices, all crude and involving black powder, arrived in packages at Fort McNair, Fort Belvoir, and the CIA. Had any of the packages exploded, the official added, they would not have been able to cause any fatalities. At least one package was sent to the National Defense University at Fort McNair, CNN reports, arriving in the morning. The package went through a scanning machine, and as soon as it was discovered to contain explosive material, the building was evacuated. No one was injured.
All of the suspicious packages are now being examined at the FBI's lab in Quantico, Virginia.
