At least one person has died after two helicopters crashed in New Jersey on Sunday afternoon, according to local news reports, citing US officials.
The Federal Aviation Administration (FAA) reported that Enstrom F-28A and Enstrom 280C helicopters collided in mid-air near the airport in the small town of Hammonton. The pilots were the only people aboard each chopper, it said.
One was killed, while the other was rushed to a hospital with life-threatening injuries, Fox29 Philadelphia reported.
On a video circulating on social media purporting to show the incident, one helicopter spins out of control before crashing.
In other footage, a plume of smoke can be seen rising from one of the purported crash sites.
According to the FAA, the US National Transportation Safety Board is taking over the investigation, and will provide further updates.
