The Tesla Cybertruck explosion and fire at the entrance of the Trump Hotel in Las Vegas Wednesday morning is being investigated as a possible terrorist act, according to a law enforcement official who has been briefed on the investigation.

A Tesla Cybertruck exploded outside Trump International Hotel Las Vegas' entrance on Wednesday, killing the driver and wounding seven people, law enforcement officials said. The big picture: Clark County/Las Vegas Metropolitan Police Sheriff Kevin McMahill said at a Wednesday afternoon briefing that "camp fuel canisters and large firework mortars" were found in the back of the truck.

The explosion was caused by fireworks and explosives in the bed of the rental Cybertruck, which had no faults, according to data.
