MANILA — The International Criminal Court (ICC) has called on individuals who witnessed the alleged killings and abuses linked to the Philippines’ war on drugs from 2011 to 2019 to come forward and provide information for its ongoing investigation.

The ICC earlier launched a microsite where direct witnesses, including members of the Philippine National Police (PNP), may contact the Office of the Prosecutor and submit initial information relevant to the probe.

“The Office of the Prosecutor of the International Criminal Court is investigating allegations of crimes against humanity, including killings, torture and sexual violence, perpetrated as part of the so-called War on Drugs campaign, between 1 November 2011 to 19 March 2019,” the ICC said Friday.

“The Office is appealing for direct witnesses to these incidents, including members of the Philippine National Police (PNP) and other law enforcement agencies who were involved in these incidents, to come forward and speak with members of the Office,” it added.

The Office of the Prosecutor said witnesses may provide their testimonies confidentially through https://appeals.icc-cpi.int.

PNP Public Information Office chief Brig. Gen. Randulf Tuaño, in a message to reporters, said any police officer considering testifying “should seek legal advice since the call from ICC is an appeal, not a compulsion.”

Former President Rodrigo Duterte has been in ICC custody since March 12, 2025, after he was surrendered under an arrest warrant related to alleged crimes connected to the government’s anti-illegal drugs campaign.

The ICC earlier denied requests for Duterte’s interim release in September 2025, which were later upheld on appeal in November. The court said it will set the schedule for a hearing on the periodic review of his detention at a later date.
