Which former head of state appeared in person before the International Criminal Court in September 2026 over a drug war?

Explanation: Former Philippines president Rodrigo Duterte appeared in person at the International Criminal Court in The Hague facing three counts of crimes against humanity over his anti-drug campaign. Prosecutors allege he created, funded and armed death squads that killed as many as 30,000 people.
