By Hyunsu Yim and Jack Kim SEOUL (Reuters) -South Korean police raided the office of President Yoon Suk Yeol, a presidential security official said on Wednesday, in a widening investigation into the embattled leader's failed attempt to impose martial law.

South Korean President Yoon survived an impeachment motion after members of his party boycotted the vote. Yoon attempted to impose martial law earlier this week, sparking backlash.

South Korean opposition lawmakers are pushing to hold an impeachment vote on Saturday against President Yoon Suk Yeol as the fallout from his short-lived declaration of martial law continues.
