According to NBC News, the FBI is investigating an attack on a base in California. In the attack, a vehicle possibly packed with propane tanks crashed through the main gate.
The attack took place on the Travis Air Force Base in California. The tanks exploded, killing the driver, base officials said Thursday according to NBC.
During their investigation, detectives from the FBI and Air Force Office of Special Investigations identified the motorist responsible for the explosion. They said the motorist had "unauthorized access," but they did not release that person's name or a possible motive for the mayhem.
Lt. Greg Hurlbut of the Fairfield Police Department described the attack as "a unique and unusual situation." The explosion erupted shortly after the vehicle breached the gate around 7 p.m. PT on Wednesday.
After first responders put out the flaming vehicle, the driver was pronounced dead at the scene. The vehicle appeared to be either a truck or an SUV.
"A robot was used to make sure there were no unexploded military supplies in what was left of the vehicle before the area was declared safe," added NBC.
Videos posted on Facebook show the vehicle in flames inside the gate. Thick gray smoke dramatically billows into the sky.
According to a witness, the vehicle was carrying propane tanks when it approached the gate of the Travis Air Force Base.
The witness says the driver "started messing with a fuel ignition source to blow the propane tanks" before driving to the side of the road, "where he burned to death," the account said.
"We didn't know if it was a terrorist attack or a suicide, but we were using the word Bomb for the incident."
NBC News said they hadn't verified the authenticity of the video or the Facebook accounts. However, they said the page where it was posted is a "well-established forum widely used by airmen and non-commissioned officers, and its contents are moderated."
The commander of the base released a statement about how they will be dealing with the incident. He emphasized how they will prioritize the safety of everyone at the base and in the local community.
The base, which is about 30 miles southeast of Sacramento, employs more than 26,000 active-duty, reserve, and civilian personnel.
