FBI warns of terrorist attack by drones

The FBI has warned that takfiri groups may use their wartime knowledge to transform commercially available drones into deadly weapons in the United States, the Newsweek magazine said on Wednesday.
In a written testimony submitted Wednesday to the Senate Homeland Security and Governmental Affairs Committee, FBI Director Christopher Wray warned that the "threat from Unmanned Aircraft Systems [UAS] in the US is steadily escalating", the magazine reported.
He said drones "may encourage use of this technique in the US to conduct attacks."
Though President Donald Trump mocked Venezuela's reaction to the suspected attempt on the left-wing leader's life, experts have warned that the threat of such an attack being conducted in the US was very real—and that authorities may not be adequately prepared.
US al-Qaeda sympathizer Rezwan Ferdaus was sentenced to 17 years in federal prison in 2012 over his plan to attack the Pentagon and the Capitol building with a remote-controlled plane the previous year. He sought to use his physics degree to equip the device with explosives but was caught when he unknowingly reached out to undercover FBI agents for supplies.
