A GREEN Beret shot himself before he exploded a device in a Tesla Cybertruck outside the Trump International Hotel in Las Vegas, authorities have said.

The explosion caused minor injuries to seven people and only minimal damage to the hotel. 

US special forces serviceman Matthew Livelsberger probably planned a more damaging attack but the blast was mostly limited to the interior of the vehicle because the explosion “vented out and up” and didn’t hit the hotel doors just a few feet away, Clark County Sheriff Kevin McMahill said on Thursday.
