Large, often noisy, and launched from unknown locations by unidentified parties, ongoing sightings of mystery drones over New Jersey remain a problem, according to federal officials who are ramping up efforts to get to the bottom of the matter.

The sightings, which have occurred since mid-November, are currently being investigated by federal agencies that include the Federal Bureau of Investigation (FBI), Department of Homeland Security (DHS), and Federal Aviation Administration (FAA), as well as local and state law enforcement in New Jersey and surrounding states where observations of the mystery drones have occurred.

Speaking from Washington on Wednesday, Deputy Pentagon Press Secretary Sabrina Singh confirmed to reporters that the ongoing drone sightings are not linked to any U.S. military drone activities, while also confirming that the Pentagon currently has no evidence to suggest they are being controlled by foreign actors.

“At this time, we have no evidence that these activities are coming from a foreign entity, or are the work of an adversary,” Singh said yesterday, stating that the DoD was aware of no threats to U.S. military assets resulting from the drone incidents.
