Philippines President Rodrigo Duterte has said he plans to withdraw his country from the International Criminal Court (ICC) after it began examining the country’s drugs war.
A statement said the ICC inquiry was “in violation of due process”.
It also cited “outrageous attacks” on Mr Duterte and his government by the United Nations.
ICC chief prosecutor Fatou Bensouda said the court would be looking at reports of extrajudicial killings.
She stressed that the examinations by the ICC – based in The Hague – were “not an investigation” but a process of examining information “in order to reach a fully informed determination on whether there is a reasonable basis to proceed with an investigation”.
President Duterte’s policy of endorsing such killings in the drugs war has drawn widespread condemnation.
