Andrew GoudswardJune 17, 2026 — 6:22amWashington: The FBI said it thwarted a planned attack on the Ultimate Fighting Championship mixed martial arts event on the White House lawn on the weekend, taking five people into custody, according to court documents.The plot involved using explosive-laden drones to strike the north side of the White House with the aim of funnelling attendees toward an exit where snipers planned to open fire on fleeing politicians and others, the FBI alleged in court papers on Tuesday (US time).Fireworks go off during the UFC Freedom 250 event at the White House on Monday.Saul Loeb/Pool AFP via APUS President Donald Trump attended the event, which was staged without incident on his 80th birthday, along with several senior Republican lawmakers, donors and administration officials to commemorate the 250th anniversary of US independence.The five people charged appeared to subscribe to anti-government conspiracy theories and were motivated in part by anger at the handling of investigative files related to sex offender Jeffrey Epstein, according to court documents.One person charged expressed interest in targeting lawmakers who had received campaign donations from pro-Israel groups, the documents said.“On June 10, FBI and our law enforcement partners became aware of a potential threat to the UFC America 250 event in Washington, D.C. involving individuals outside of the National Capital Region,” FBI director Kash Patel said in a statement posted on X.At least three of the five taken into custody have been charged with conspiracy to commit murder. Other charges facing the group include conspiracy to commit an offence against the US and weapons offences.They have not yet entered pleas in court and attorney information was not immediately available.US President Donald Trump stands in the ring at the end of UFC event.AP Photo/Alex BrandonFox News Digital reported that the group included as many as 23 people.Authorities discovered the plot when the mother of one of the suspects, 19-year-old Tycen Proper, called local police in Ohio to report that her son had made several weapons purchases and was interacting with concerning people online.Proper later admitted to FBI agents that he was aware of a planned coordinated attack on the UFC event, according to an FBI affidavit.Trump, at the Group of Seven summit in Evian, France, said he had not heard about the planned attack. “The attack that I watched were the fighters,” he said.Vice President JD Vance said authorities were trying to look at the underground networks that would drive such violence.“Twenty-three people do not get to the point where they’re going to commit a mass terror incident in Washington, D.C. without some serious funding, without some serious coordination,” Vance said in a Fox News interview.“That’s not a few guys doing crazy stuff, that is a coordinated planned terrorist plot,” he said.From our partners
