Prosecutors on Wednesday indicted a man over an attack on Prime Minister Fumio Kishida using explosives during an election event in Wakayama Prefecture in April, after concluding that the suspect is mentally fit to be held criminally responsible.

Ryuji Kimura, a 24-year-old from Hyogo Prefecture, has remained silent since his arrest at the scene in the city of Wakayama.

While Kishida was not hurt, two people, including a police officer, sustained minor injuries.
