South Korea’s Constitutional Court has unanimously removed Yoon Suk Yeol as president after he threw the nation into turmoil by declaring martial law and sending troops to parliament in an ill-fated effort to break through legislative gridlock.

The ruling caps months of political turmoil that have overshadowed efforts to deal with the new administration of U.S. President Donald Trump at a time of slowing growth.

Impeached President Yoon Suk Yeol was removed from office four months after he declared martial law, sending troops into parliament.
