South Korea's impeached president Yoon Suk Yeol has been found guilty of abuse of power and falsifying documents over his failed martial law bid in 2024.

A Seoul court is now deliberating on whether he also obstructed the course of justice by evading arrest. Prosecutors have sought a 10-year jail term for this set of charges.

This is the first of the verdicts in four trials linked to his shock martial law decree. Although short-lived, the move plunged the country into turmoil, sparking protests as MPs rushed to the national assembly to overturn Yoon's decision.

Friday's ruling offers clues as to how the rest of Yoon's trials could go. Charges range from the abuse of power to campaign law violations.

The most serious charge is insurrection, for which prosecutors have demanded the death penalty. The verdict in that trial is expected in February.
