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.

The children of former president Rodrigo Duterte greeted him on his 80th birthday Friday as he remained at the Scheveningen prison in The Hague, Netherlands following his arrest by the International Criminal Court for alleged crimes against humanity linked to his war on drugs during his term.
