In a worst nightmare for any nation, a suspected ISIS gunman killed around 50 people in America while leaving at least 400 people injured at Mandalay Bay Casino in Las Vegas in the worst terrorist attack after 9/11. The shooting started around 11.50 am in the morning and lasted only about for 10 seconds, even as people were taken by surprise. It is estimated that some 22,000 people were there in a crowd when the gunman fired. Reports said that the gunman was a recent convert to Islam. The gunman was later identified as tephen Paddock, a 64-year-old, who killed himself before he could be arrested.
