Duterte's ICC trial to proceed

The appeals chamber's decision clears the way for prosecutors to continue their investigation into alleged crimes against humanity.

Families of the victims have hailed the ruling as a major vindication in their pursuit of justice.

Duterte, who is 81, has been held by the ICC in The Hague since March after being accused of arming death squads.

The Philippine government has previously challenged the court's authority, but the judges determined that the legal proceedings must move forward.
