Dozens of suspected drones have been spotted flying over states on the East Coast of the United States, sparking concern from local officials.

Staten Island Borough President Vito Fossella said the drones, often seen flying at night, have been spotted hovering over critical infrastructure, including Port Liberty New York near the Goethals Bridge, the Verrazzano-Narrows Bridge and Fort Wadsworth, one of the oldest military installations in the country.

Sightings of bright lights floating in the sky above New Jersey began nearly a month ago. Since then, the drones have been spotted in six US states. | ITV National News
