THE HAGUE, Netherlands May 11 (Reuters) - The International Criminal Court on Monday confirmed it had issued an arrest warrant for a longtime ally of former Philippine president Rodrigo Duterte, accusing senator Ronald dela Rosa of crimes against humanity for overseeing Duterte's war on drugs.

"This arrest warrant against Mr Ronald Marapon Dela Rosa was issued confidentially, under seal, by Pre-Trial Chamber I of the ICC on 6 November 2025. The ICC is currently in the process of unsealing the warrant of arrest. We will circulate to this group as soon as available," the ICC said in a statement.
