The vote was the second major impeachment in two weeks after President Yoon’s ill-fated martial law bid set off turmoil. The country’s currency has plunged.

SEOUL (Reuters) -South Korean investigators again asked the country's acting president on Saturday to order the presidential security service to comply with an arrest warrant for impeached President Yoon Suk Yeol.

The impeachment of South Korea’s acting President Han Duck-soo has plunged the country into further political turmoil, coming less than two weeks after lawmakers impeached President Yoon Suk Yeol.

The plane crash is the first major test for South Korea’s acting president, Choi Sang-mok, who was appointed the interim leader only on Friday, as the country grapples with a political crisis at the highest levels.

South Korea's acting President Choi Sang-mok vowed to continue trilateral cooperation with Japan and the United States, saying on Friday his country's diplomacy remains steadfast despite an unprecedented political crisis at home.

South Korean lawmakers voted on Friday to impeach acting president Han Duck Soo, barely two weeks after Yoon Suk Yeol was removed from the presidency over his imposition of martial law. A total of 192 lawmakers in the opposition-controlled parliament voted to impeach Han - significantly more than the simple majority required.

Lee Jae-myung, leader of the Democratic Party of Korea, criticized Acting President Choi Sang-mok, blaming him for the anti-corruption agency’s failure to arrest impeached President Yoon Suk-yeol. “Acting President Choi Sang-mok should be held accountable for disrupting order and acts of insurrection.

South Korea's parliament impeached acting President Han Duck-soo on Friday, less than two weeks after suspending President Yoon Suk Yeol's powers over his short-lived declaration of martial law, plunging the country deeper into political chaos.

South Korea's police have been asked to arrest suspended president Yoon Suk Yeol, the Yonhap news agency reported on Monday. Dozens of investigators working for the Corruption Investigation Office for High-ranking Officials (CIO) attempted to execute a court warrant for Yoon's detention on Friday after he ignored three summonses for questioning over his botched attempt to impose martial law on December 3.
