A man set himself on fire on Wednesday near South Korea's corruption investigation office, where impeached President Yoon Suk Yeol was being interrogated over insurrection allegations, the national fire agency said.
The man, in his 60s, was severely burned and unconscious following the incident which happened just after 8:00 pm local time (1100 GMT), the fire agency said.
Yonhap news agency had earlier reported that the man had died.
Scores of people protesting Yoon's arrest, related to his stunning decision to declare martial law on December 3 that plunged the country into political turmoil, were still gathered outside the offices at the time of the incident.
