The active shooter situation occurred in a shopping center in Korat, also known as Nakhon Ratchasima, in northeast Thailand. The suspect, reportedly an Army sergeant, used an assault rifle to kill at least 17 people in area. Several others are wounded.

According to reports, the gunman has taken hostages on the fourth floor of the mall and Thai special forces are preparing to storm the building.

A video posted to social media show people fleeing the scene as security forces stand guard outside the mall. In another clip, a large fire burns near the building.

Local media have reported that the shooter took selfies and livestreamed during the attack. One of the purported photos shows the suspect wearing a combat helmet and a face mask as he holds up an assault rifle.

Social media users posted what appear to be short clips of a livestream, with the suspect panning the camera to show the area around him. The gunman reportedly posted status updates on Facebook during his rampage, including “Should I surrender (give up)?” and “Well I stopped already.” Before carrying out the attacks, he posted an image of a pistol with bullets, captioning the photo: “It’s time to get excited.”

His Facebook page was shut down shortly after he began the attack.
