Japanese authorities have launched an investigation after a small drone reportedly containing traces of radiation was found on the roof of the prime minister’s office, sparking concerns about drones and their possible use for terrorist attacks.
No injuries or damage was reported from the incident on Wednesday. The prime minister, Shinzo Abe, who is at present in Indonesia, works at the building during the day and commutes from his own private home roughly 15 minutes away.
Police said it was not immediately known who was responsible for the drone.
The significance was not immediately clear, but a Japanese court on Wednesday approved the restart of a nuclear power station, rejecting nuclear power safety worries in the wake of the 2011 Fukushima radiation disaster.
