Guests and employees at the Hyatt Ziva Riviera resort in Cancun, Mexico, were told to hide amid reports of armed men in the area on Thursday, according to reports from guests at the hotel.
Former NBC executive Mike Sington – who was staying at the resort – told Insider that he started hiding about 4 p.m. EST.
Sington posted a video on Twitter showing employees sheltering.
Sington later wrote that there was a shooter on the property on the Riviera Maya and that employees were hugging each other.
Paramedics are also on the scene, Sington said. By 4:40 p.m. EST Sington said guests and the employees were taken out of hiding but hadn't gotten an update from employees at the resort.
Andrew Krop said his husband was staying at the hotel and reported that "men had stormed the beach with machine guns and started firing."
Krop's husband ran with friends are were hiding in a locked room.
An official at the US embassy in Mexico told Insider that the US consulate and local authorities were aware of the reports, but couldn't verify if they were accurate.
"We are aware of the situation and our office there is working with local law enforcement," the embassy official said.
Calls to local police in the area weren't immediately returned and no one picked up at the resort when contacted by Insider.
