The Islamic State of Iraq and Syria (ISIS) claimed to be responsible for the Las Vegas shooting. According to the experts, the announcement shows the growing desperation of the terrorist group, which is losing territories in Iraq and Syria, NBC News reported. The claim came after 64-year-old Stephen Craig Paddock, of Nevada, shot into thousands of fans during the concert in Las Vegas on Sunday night. More than 500 people were injured and at least 59 died.

Stephen Paddock committed suicide, shooting himself before the officials opened the door of his closed hotel room.

This is the story that has been widely reported since the incident became national news.

What ISIS said

According to a counterterrorism expert Peter Vincent, ISIS took false responsibility for the attack. ISIS stated that Paddock was its soldier, but did not provide any evidence for it. Vincent said in the statement “It’s a sign of their sheer desperation,” adding that ISIS was “fractured and damaged.” ISIS lost oil reserves and has difficulties with self-funding.

Stephen Paddock's brother, Eric Paddock, stated that the gunman had “no religious affiliation, no Political Affiliation,” and no history of any Mental illness.

Experts announced their opinion

The FBI did not take into account ISIS's Amaq propaganda agency's announcement that Paddock attacked “in response to calls to target coalition countries,” the Independent reported.

In its second statement, ISIS explained that Paddock had an Islam name, Abu Abd el-Bar al-Amriki” and converted to Islam some months ago.

According to the experts, Paddock acted alone. The FBI is investigating the analysis of Paddock's phones and computers. The FBI agent Aaron Rouse said that “We have determined at this point no connection to the international terrorist organization,” the Sun reported.

Todd Fasulo, Assistant Clark County Sheriff, said that Paddock is "solely responsible for this heinous act."

NBC News security analyst Duncan Gardham said that by making false claims, people will stop taking ISIS seriously. At the same time, deputy director of the International Centre at King’s College London, Shiraz Maher, said that the claim did not show the group's weakness.

He said that the terrorist group had intended to spread panic, possibly to hinder the investigation and inspire troops. Maher noted that it could be "a form of psychological warfare."
