Former Philippine President Rodrigo Duterte has been put on a plane to The Hague following his arrest on an International Criminal Court (ICC) warrant, his daughter and local outlet The Philippine Star have reported.

MANILA, Philippines (AP) — A plane carrying arrested former Philippines President Rodrigo Duterte left Manila Tuesday night for him to be turned over to the International Criminal Court in The Hague which has ordered his arrest for alleged crimes against humanity, President Ferdinand Marcos said.

Rights groups say tens of thousands of unarmed suspects were murdered in extrajudicial killings during Duterte’s war on drugs.
