Former Philippine president Rodrigo Duterte was arrested today.

The Philippine government says he was picked up on an Interpol arrest warrant from the International Criminal Court amid accusations that he committed crimes against humanity during his war on drugs.

The 79-year-old, who left office in 2022, was arrested at the International Airport in Manila after his arrival from Hong Kong.

Rights groups say tens of thousands of unarmed suspects were murdered in extra judicial killings during Duterte’s campaign against narcotics dealers, allegations he has denied.

Though the Philippines has not been a member of the International Criminal Court since it withdrew under Duterte in 2019, president Ferdinand Marcos, Jr. previously said his government would cooperate if Duterte’s arrest were sought by international police.
