South Korea’s impeached president, Yoon Suk Yeol, has been formally arrested, days after being apprehended at his presidential compound in Seoul.

China will make every effort to rescue Chinese nationals who fell foul of scam operations luring them to countries including Myanmar, the public security ministry said late on Wednesday.

Yoon’s detention, after a tense standoff outside the presidential residence, marks the latest chapter in a bewildering series of events since his martial law decree.
