South Korea on Tuesday imposed a travel ban on former Premier Han Duck-soo and former Finance Minister Choi Sang-mok, local media reported.
The travel ban followed their questioning by the police on Monday over their alleged involvement in ousted President Yoon Suk Yeol's short-lived martial law decree on Dec. 3 last year, according to Korea JoongAng Daily.
The police also questioned former Interior and Safety Minister Lee Sang-min on Monday.
Choi, who had also served as the acting president from December 2024 to March 2025 following the impeachment of Han Duck-soo, resigned earlier this month ahead of an impeachment motion in parliament.
