At least three people have been killed, and nine others injured as a knife-wielding attacker went on a rampage in the Taiwanese capital, Taipei.
Taiwanese Premier Cho Jung-tai said the 27-year-old suspect set off smoke bombs at Taipei's main metro station, before running to another station in a busy shopping district, stabbing people along the way.
Jung-tai added that the suspect, named by officials as Taiwanese man Chang Wen, later died after falling from a multi-storey building.
His motive remains unclear.
Attacks of this kind are rare in Taiwan, which has low rates of violent crime, as the last time a similar incident struck Taipei was more than a decade ago in 2014.
Videos shared on social media show people fleeing the scene in panic as an individual wearing a baseball cap and black clothing lobs smoke bombs across a busy road.
He can then be seen carrying a large knife as he walks past several cars.
Jung-tai says the suspect had detonated smoke bombs and Molotov cocktails at Taipei's Main Station, which is connected to a busy underground shopping street.
A man reportedly tried to stop the attacker but was struck with a blunt object and later died in the hospital.
