A man threw several firebombs at the headquarters of Japan's ruling party on Saturday, Japanese media report. No one was injured in connection with the incident.
The man was arrested outside the building in Tokyo after he crashed his car into a nearby fence. The police are tight-lipped about the case, which is still under investigation, and the motive behind the attack is still unclear.
The ruling Liberal Democratic Party's popularity has declined among the general public after being linked to several corruption scandals. With only just over a week left until the upcoming parliamentary election, the party is struggling with low opinion polls, but it is still unclear whether they will lose their grip on parliament. The opposition in Japan is divided.
The Liberal Democrats have ruled almost uninterrupted for the past decades. The party has not commented on the attack.
