Two Naval facilities that were evacuated Tuesday morning after an unspecified threat have been given the all-clear by authorities, 6ABC is reporting.

The Navy Yard in Philadelphia and The Naval Support Activity Philadelphia were evacuated around 11 am, according to multiple reports.

Officials tell 6ABC the threat that prompted the evacuations was later found to be non-credible.

The Navy Yard, via its official Twitter page, confirmed the evacuations Tuesday morning.

“The U.S. Navy has received national security info leading them to dismiss its employees for day,” The Navy Yard Tweet said.

The threat level for both facilities was raised from Bravo to Charlie due to the threat, NBC10 said.
