Last week, a mix-up involving a U.S. drone flight caused confusion between South Korean and U.S. militaries, according to a South Korean military official. The incident occurred when South Korean forces detected the U.S. spy drone over an inter-Korean border area, mistaking it for an enemy threat and nearly preparing to shoot it down.

Seoul stocks experienced a significant drop of over 5 percent on Monday, as investors took profits from semiconductor heavyweights following a record surge the previous day.

Discrepancies were found between the number of voters who cast ballots and the official vote counts from the June 3 local elections. It is possible that these gaps could indicate a new form of data manipulation by the National Election Commission (NEC). Yonhap News Agency analyzed the voting data and discovered inconsistencies at 78.9 percent of Seoul's 427 administrative districts.

The South Korean won weakened against the U.S. dollar on Monday as overseas investors sold local stocks. The won was quoted at 1,429.8 won per dollar at 3:30 p.m., a decrease of 5.8 won from Friday's onshore trading close.
