Former Philippine President Rodrigo Duterte is marking his 80th birthday in detention in the Netherlands after the International Criminal Court ordered his arrest.

Family and supporters of former President Rodrigo Duterte will rally Friday to mark his 80th birthday and protest his detention in The Hague on a charge of crimes against humanity. Duterte could spend the remainder of his life in jail if convicted at the International Criminal Court (ICC) of the charge tied to his “war on drugs” in which thousands were killed.

Philippine officials on Thursday defended before the country's Senate the arrest and transfer to the International Criminal Court of former President Rodrigo Duterte, as they faced allegations he was illegally abducted at the behest of a foreign institution.
