South Korea's parliament passed a bill Tuesday to appoint a standing special prosecutor and investigate President Yoon Suk-yeol's treason charge, TV footage showed Tuesday.

Among 287 National Assembly lawmakers attending the plenary session, 210 voted in favor and 63 against, with 14 abstentions.

The bill was submitted to the 300-member unicameral parliament last week to get to the bottom of Yoon's rebellion charge caused by his "unconstitutional" martial law declaration.
