The International Criminal Court has started pre-trial hearings on former Philippine President Rodrigo Duterte, who is facing three counts of crimes against humanity for deadly anti-drugs crackdowns he oversaw while in office. The evidence will detail his alleged involvement in dozens of killings as part of his so-called war on drugs. The ex-leader is facing three counts of crimes against humanity for deadly crackdowns he oversaw first while he served as mayor of the southern Philippine city of Davao and later as president. Rights groups and families of victims hailed Duterte’s arrest in March. Monday's hearing is not a trial, but allows prosecutors to outline their case in court.
