Japan PM Fumio Kishida evacuated after what appears to be smoke bomb thrown

A man was detained at the scene in Wakayama, where Mr Kishida had been due to give a speech, local media reported.

A witness said they saw a person throwing something, followed by smoke, while another said they heard a big bang. No injuries were reported.

Video showed officers piling on top of a person, believed to be a suspect.

He was arrested on suspicion of obstruction of business and later identified by the authorities as 24-year-old Ryuji Kimura. His motivation is still unclear.

Japan's public broadcaster, NHK, quoted Mr Kishida as saying there was a "loud blast" at the venue. "Police are investigating details, but I'd like to apologise for worrying many people and causing them trouble."
