The National Police Agency held its first expert panel meeting on Tuesday on countering illegal drone flights amid rising concerns over their potential use in terrorism and other threats. The National Police Agency on Tuesday held the first meeting of an expert panel on measures against illegal drone flights, in light of the growing threat of drones being used for terrorism and other purposes. The panel plans to compile a report by the end of the year on expanding the list of no-fly zones and penalties, with a view to revising the drone control law. The law was established in 2016 in the wake of an incident in which a drone fell on the roof of the Prime Minister's Office in Tokyo. It currently bans drone flights within about 300 meters of important facilities such as the National Diet Building, the Imperial Palace and nuclear power plants.
