According to a report by the Associated Press in a tweet, the Islamic State (ISIS) has claimed responsibility for Las Vegas terrorist attack, saying that the shooter converted to Islam months ago.
Authorities identified Stephen Paddock as the 64-year-old domestic terrorist who opened fire on concert attendees of the Route 91 Harvest Festival in Las Vegas on Sunday night, but his conversion to Islam has yet to be substantiated.
In its claim, ISIS said that the perpetrator was "a soldier" who had converted to Islam months ago, while releasing two statements on its Aamaq news agency on Monday. Neither report specifically named Paddock, but read that he had "executed the operation in response to calls to target countries of the coalition" batting the extremist group in Iraq and Syria.
ISIS has often made claims on attacks by individuals inspired by its message, but with no tangible links to the group.
ABC News spoke to the brother of the shooter, Eric Paddock, who said that his brother lived his life "like an open book," and that the casinos in the area "knew his brother very well."
