SEOUL, South Korea (AP) — South Korea’s main liberal opposition party said Tuesday it will seek to impeach acting leader Han Duck-soo, as Seoul grapples with the turmoil set off when impeached President Yoon Suk Yeol made a short-lived declaration of martial law.

South Korea's main opposition party vowed on Tuesday to impeach acting president Han Duck-soo but reversed an earlier plan and decided to wait until later in the week, party officials said, as the risk of further political uncertainty heightened.

South Korea's military said on Monday it has detected signs of North Korea preparing to send more troops and weapons, including suicide drones, to Russia to support its war against Ukraine.

South Korea's consumer sentiment dropped sharply this month to hit the weakest level in more than two years on growing worries about political uncertainty following parliament's impeachment of President Yoon Suk Yeol.

American consumers are feeling less confident in December, a business research group says. The Conference Board said Monday that its consumer confidence index fell back in December to 104.7 from 112.8 in November.
