Investigators have so far found "no connection" between an international terrorist group and a mass shooting in Las Vegas that killed at least 58 people and injured more than 515, an FBI special agent said Monday.

Daesh, through its propaganda arm, had earlier claimed responsibility for the attack, claiming the shooter was a recently converted "soldier." Police said the attack was carried out by Stephen Paddock, a 64-year-old retired accountant. He killed himself after the shooting.

"As this event unfolds we have determined to this point no connection with an international terrorist group," said Aaron Rouse, the special agent in charge of the Las Vegas office of the FBI.
