The victims burned to death or died from smoke inhalation. Some sources declared that the three assailants were earlier denied entry to the club before returning on the motorcyle. Flames were burning the inside of the building and charring the facade. The fire was quickly extinguished and security authorities are investigating the attack. An official told to the media that one of the suspects was an employee of the restaurant that was attacked. An initial investigation had revealed no terrorism link to the attack even if in the past Egypt has been hit by a wave of terror attacks by Islamic extremist groups including the Egyptian branch of the Islamic State of Iraq and Syria.
