Two Republican Jersey Shore-area congressmen, U.S. Reps. Chris Smith and Jeff Van Drew, have called on the military to shoot down the drones. However, Pentagon spokeswoman Sabrina Singh told reporters Wednesday that “our initial assessment here is that these are not drones or activities coming from a foreign entity or adversary.”

Weeks of unexplained drone sightings in New Jersey have left residents, politicians and public safety officials scratching their heads, prompting security concerns.

A large number of mysterious drones have been reported flying over parts of New Jersey and the East Coast in recent weeks, sparking speculation and concern over who sent them and why.

The FBI and Department of Homeland Security said on Saturday that ongoing investigations around reported drone sightings over New Jersey have found many reports are, in fact, manned aircraft.
