South Korean anti-graft investigators were waiting on Tuesday for a new court-ordered arrest warrant for impeached President Yoon Suk Yeol, whose failed martial law bid threw the country into turmoil.

Thousands of South Korean citizens were gathering on Sunday near impeached President Yoon Suk Yeol’s residence a day before an arrest warrant for him expires.

As Yoon continues to stonewall efforts to investigate his martial law declaration last month, the political crisis in South Korea is deepening.
