President Yoon Suk-yeol hit back at the main opposition party on Thursday over allegations his administration masterminded the prosecution's attempted raid of its headquarters, saying the people will be the judge of whether such claims are justified.

Prosecutors swooped down on the Democratic Party of Korea (DPK) headquarters in Seoul on Wednesday as part of an investigation into whether a close aide to DPK leader Lee Jae-myung took illegal political funds but withdrew after a standoff with party officials.

The DPK has denounced the investigation and other investigations into members of the previous Moon Jae-in administration as a political reprisal and an attempt to suppress the opposition party.

"As far as investigations are concerned, I only know what I see in press reports, and as far as the details, I'm not free enough to look into investigation details," Yoon told reporters as he arrived for work.
