Nearly two months have also passed since the President named the PDEA as the sole agency in charge of the fight versus illegal drugs.
Presidential spokesman Harry Roque previewed elements of a speech he is due to deliver at the ICC headquarters in NY on Wednesday, Efe news reported.
"Since the police were withdrawn from anti-drug operations in October, there has been a marked decline in the number of deaths resulting from these operations".
"PDEA remains the lead agency but the PNP will again participate in the anti-illegal drug operations", he added.
Philippine police on Tuesday were ordered to rejoin the war on drugs, overturning President Duterte's decision two months ago to leave the campaign in the hands of the government's anti-drug agency.
Other law enforcement agencies, including the National Bureau of Investigation, Armed Forces of the Philippines, Bureau of Customs and the Philippine Postal Corporation were also directed to provide support to the PDEA in the conduct of the anti-narcotics campaign. While they were away, the PNP's Drug Enforcement Group conducted trainings for drugs operations in anticipation for the day they come back.
However, he said PDEA has been seriously hampered in performing its huge mandate by lack of resources, specifically agents and operatives who can penetrate drug-infected areas down to the municipal and village levels.
Duterte had removed police from anti-drug operations following criticism from human rights advocates, foreign governments and the United Nations after thousands of drug suspects were killed during the campaign and local street protests took place when three teenagers were killed in the crackdown. Several witnesses, including the taxi driver, claimed to have witnessed the killing.
Dozens of minors are being shot dead as Philippine President Rodrigo Duterte continues his war on drugs, according to a recent study.
