The International Criminal Court said Wednesday it will open a full investigation into possible crimes against humanity committed as part of Philippines President Rodrigo Duterte’s brutal war on drugs. After weighing evidence on more than 200 victims, the ICC’s judges found evidence that a “widespread and systematic attack against the civilian population took place” and that Philippine authorities “failed to take meaningful steps to investigate or prosecute the killings.” Last year, a United Nations report found at least 8,600 people have been killed in the drug war unleashed by Duterte, with some estimates suggesting the true toll could be three times higher.
