The mysterious reported sightings of drone clusters in the night skies over New Jersey and other parts of the US north-east has prompted frustrated outbursts from Congress members, triggering calls for a limited state of emergency to be declared over the region.

Jon Bramnick, a Republican state senator in New Jersey, has demanded a ban on all drones until the mystery is solved. ABC’s Action News reported that he called for a “limited state of emergency … until the public receives an explanation regarding these multiple sightings”.
