The International Criminal Court has had former Philippine President Rodrigo Duterte arrested on a warrant containing charges of murder as a crime against humanity over deadly anti-drugs crackdowns he oversaw while in office.

The arrest of former Philippines President Rodrigo Duterte has given a timely boost to the International Criminal Court, which is facing U.S. sanctions and an investigation into alleged sexual misconduct by its chief prosecutor.

The arrest represents a significant victory for the I.C.C., but only a narrow set of circumstances made it possible.
