The Philippine Drug Enforcement Agency (PDEA) refuted the International Criminal Court’s findings after the tribunal said it found “reasonable basis to believe” President Rodrigo Duterte’s bloody drug wars perpetrated crimes against humanity.

ICC Prosecutor Fatou Bensouda’s office earlier said that it was “satisfied” the information that crimes against humanity were committed in the country’s anti-narcotics operations since Duterte assumed presidency in 2016.

But the PDEA said the tribunal’s findings are “solely on the basis of open-source information.”

The PDEA stressed the international court should have waited for the release of the report of the country’s inter-agency panel molded by the Department of Justice to probe the drug-linked killings “rather than issuing general statements that are yet to be proven without the aid of a formal and local investigation.”

The agency cited the resolution of the United Nations Human Rights Council (UNHRC), which would provide technical cooperation and capacity-building for promotion and protection of human rights in the Philippines instead of launching an independent investigation.
