US law enforcement said it had thwarted an alleged plot to attack the White House during a crowded MMA event attended by President Donald Trump and other top officials.
According to US media, five people have been arrested and investigators have identified 23 people in a 'potential network of plotters' who communicated in a Signal group chat.
The group allegedly planned to detonate explosive-laden drones over the UFC arena on the White House lawn where the fights were held on Sunday and then have snipers open fire on targets in the crowd.
US correspondent Dan Mitchinson says the suspects were thwarted before the attack took place, but it was close call.
