The ICC said it would pursue an investigation of suspected crimes against humanity related to Duterte's role in overseeing a bloody "war on drugs."

Former Philippine President Rodrigo Duterte was served with an Interpol arrest warrant from the International Criminal Court in Manila on Tuesday morning local time, local officials said. The big picture: The ICC in 2021 formally authorized an official investigation into alleged crimes against humanity during Duterte's war on drugs when he was president.

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