South Korea's president faces treason probe, impeachment vote
The controversy stems from Yoon's decision to impose martial law on Tuesday night, a move he rescinded within hours after lawmakers overwhelmingly rejected it.
South Korean President Yoon Suk Yeol is under investigation for treason charges following his controversial attempt to impose martial law, a move that has also triggered an impeachment vote.
A special police team is examining complaints filed by the minor opposition Rebuilding Korea Party and a group of 59 activists, according to Yonhap news agency.
The complaints also target former Defense Minister Kim Yong-hyun, Army Chief of Staff Gen. Park An-su, and Interior Minister Lee Sang-min, accusing them of treason and related offenses.
Martial backlash
The controversy began on Tuesday night when Yoon declared martial law, citing alleged threats from the DPRK and the need to safeguard national security.
The decision, however, was swiftly rejected by lawmakers, leading to its withdrawal within hours.
Critics have condemned the move as an abuse of power, accusing Yoon of attempting to consolidate authority under the guise of addressing security concerns.

In response, six opposition parties, led by the Democratic Party, filed an impeachment motion against Yoon and Kim.
The impeachment vote is scheduled for Saturday. Kim, who has since resigned, has been banned from leaving the country, while Yoon faces mounting political and legal challenges.
Complaints against him have also been lodged with the prosecution and the Corruption Investigation Office for High-ranking Officials.
Power Struggle
The failed martial law attempt has drawn comparisons to South Korea's authoritarian past, with opposition lawmakers and activists accusing Yoon of undermining democratic principles.
The backlash reflects growing frustration with Yoon's leadership amid declining approval ratings, legislative gridlock, and allegations of authoritarian tendencies.
