Official figures showed that more than 3,300 suspects of dealing in and using drugs have been killed since Duterte took office on June 30. Philippine police has operated nearly 19,000 search operations for drug criminals and arrested over 18,000 suspects, while more than 700,000 people gave themselves up over drug-related crimes.
