UNITED NEWS INTERNATIONAL (UNI) — Philippine President Rodrigo Duterte threatened to arrest an International Criminal Court prosecutor if she enters the Philippines.

Addressing ICC prosecutor Fatou Bensouda on April 13, Duterte said, “You cannot exercise any proceedings here without basis. That is illegal and I will arrest you.

The ICC launched a preliminary investigation into alleged human rights violations committed during Duterte’s war on drugs.

The Philippine National Police say 4,021 drug suspects died during anti-drug operations between July 2016 and February of this year.

Human rights groups allege the death toll is much higher than that, and that many of the deaths were extrajudicial killings.

However, Duterte said Friday the ICC has has no jurisdiction to investigate the claims because he pulled out of the treaty that created the court.

Duterte specifically threatened Bensouda with arrest because she launched the investigation.
