3:44 One person died and seven others were injured on Wednesday when a Tesla Cybertruck that appeared to be carrying fireworks caught fire and exploded outside a Trump hotel in Las Vegas, authorities said. Social Sharing Firework mortars and camp fuel canisters were found stuffed into the back of the Tesla Cybertruck that exploded outside U.S. president-elect Donald Trump's Las Vegas hotel early Wednesday, killing a person inside the vehicle and sparking an intense investigation into possible terrorism. Las Vegas Metropolitan Police and Clark County Fire Department officials said that a person died inside the futuristic-looking pickup truck and seven people nearby had minor injuries and several were taken to a hospital. By late Wednesday afternoon, authorities were still working to get the body out of the vehicle and start processing the evidence inside. U.S. President Joe Biden was briefed on the explosion. "Our No. 1 goal is to ensure that we have the proper identification of the subject involved in this incident," said Jeremy Schwartz, acting special agent in charge for the FBI's Las Vegas office. "Following that, our second objective is to determine whether this was an act of terrorism or not."

A Turo spokesperson did not immediately respond to the AP's emailed request for comment. McMahill said video captured at Tesla charging stations provided by CEO Elon Musk helped authorities track the vehicle's journey, arriving in Las Vegas about 7:30 a.m., then driving about an hour later into the valet area of the Trump International Hotel, where it sat for 15 to 20 seconds before the explosion occurred.

The truck bed walls were still intact because the blast shot straight up rather than to the sides. 'Never seen anything like this,' Musk says Musk said Wednesday afternoon on X, "We have now confirmed that the explosion was caused by very large fireworks and/or a bomb carried in the bed of the rented Cybertruck and is unrelated to the vehicle itself. All vehicle telemetry was positive at the time of the explosion." Musk said in an earlier post on the platform that his entire senior team was investigating the explosion, adding, "We've never seen anything like this." Musk has recently become a member of Trump's inner circle and attended a New Year's Eve party at the Trump's Mar-a-Lago resort in Florida that the president-elect did not attend.

"So there's obviously things to be concerned about and it's something we continue to look at." The truck explosion came hours after a driver rammed a truck into a crowd in New Orleans' famed French Quarter early on New Year's Day, killing at least 15 people before being shot to death by police. That crash was being investigated as a terrorist attack and police believe the driver was not acting alone. "We are absolutely investigating any connectivity to what happened in New Orleans as well as other attacks that have been occurring around the world," said Sheriff McMahill. "We aren't ruling anything out." Witness heard 3 explosions
