International Criminal Court clears investigation into Philippines' 'war on drugs' deaths despite Manila's objections

The ICC had approved an investigation but suspended it after the Philippines said it was already investigating.
The ICC later ruled the Philippines' investigations were insufficient and resumed its inquiry.
An ICC appeals panel rejected the Philippines' attempt to block the investigation.
Over 6,000 people have been killed in the anti-drug crackdown, but rights groups say the number could be higher.
Former President Duterte, who oversaw the "war on drugs," withdrew the Philippines from the ICC but it still has jurisdiction over past alleged crimes.
