The FBI thwarted an attack by drones carrying explosives at an UFC event at the White House, Fox News reports. According to the TV channel, the drones were supposed to hit buildings near the venue and trigger a mass evacuation, as well as direct crowds toward a group of snipers placed in advance. After that, participants of the “second wave,” it is claimed, were supposed to storm the gates of the White House. Investigators identified 23 possible individuals involved in the conspiracy.
