South Korea's previous defense minister was stopped from attempting suicide while in detention over last week's martial law declaration, officials said Wednesday, as President Yoon Suk Yeol's office resisted a police attempt to search the compound.

The main liberal opposition Democratic Party is pushing for a new motion to impeach Yoon for his Dec. 3 decree that imposed martial law in South Korea for the first time in more than four decades. Its first impeachment attempt against Yoon last Saturday failed after ruling party lawmakers boycotted the vote. The party said it plans to submit the new motion on Thursday to set up a vote on Saturday.
