Japanese prime minister safe after blast heard at speech

Japanese Prime Minister Fumio Kishida was evacuated from a port in Wakayama after someone threw an explosive device in his direction, but he was unharmed in the incident, local media reported Saturday.

Several reports, including by Kyodo news agency, said an apparent "smoke bomb" had been thrown but there were no signs of injuries or damage at the scene. It wasn't immediately clear what the explosive device was or how many the suspect had.

A young man believed to be a suspect was arrested Saturday at the scene after he allegedly threw "the suspicious object," Chief Cabinet Secretary Hirokazu Matsuno told reporters. Matsuno refused to comment on the suspect's motive and background, saying police are still investigating.
