South Korea's Yoon faces 30-year sentence

The sentencing request follows Yoon's earlier conviction for rebellion, for which he is already serving a life sentence.

Prosecutors argued on Friday that the drone operation was a deliberate attempt to escalate tensions with Pyongyang for domestic political gain.

The case has deeply divided the country, as Yoon continues to appeal his previous convictions.

The trial underscores the ongoing challenges to South Korea's democratic institutions following the political turmoil of the past two years.
