At least 25 more drug suspects were killed overnight from late Thursday to early yesterday across metropolitan Manila, bringing the total number killed so far to 85 in the bloodiest week since President Rodrigo Duterte kicked off his anti-narcotics war last year.
The spike in deaths came as Mr Duterte cheered on lawmen involved in anti-drug operations with promises of immunity, promotion, commendation, a reward of 2 million pesos (S$53,000) and a holiday to Hong Kong.
Human rights activists and opposition politicians condemned what they saw as a disturbing escalation in extrajudicial killings, but the nation's police chief said the drug raids will continue.
Director-General Ronald de la Rosa said the spike in killings was "normal… because the operations are large-scale".
Police had yet to release an official tally yesterday, but online news site Interaksyon reported that 18 were killed in a cluster of four cities known as the Camanava area, north of the capital Manila. Seven more were killed in Manila and Quezon City, according to the Philippine Daily Inquirer.
These deaths added to 60 killed from Monday in Manila and nearby Bulacan province in a renewed crackdown - dubbed by police as "one-time, big-time" operations - that Mr Duterte had praised.
On Thursday, Mr Duterte reassured law enforcers they would not go to jail.

These latest killings have sparked outrage, even among Mr Duterte's allies in Congress, as one of the victims was a 17-year-old boy.

Vice-President Leni Robredo, who leads the opposition party, condemned the killings yesterday.
She said: "We have been disgraced by this culture of impunity a long time ago… It should not happen."
Mr Chito Gascon, head of the human rights commission, said Mr Duterte's threats against those pushing to investigate the killings "exacerbates the climate of impunity that has characterised this administration".

It added: "Unless he addresses the roots of the proliferation of illegal drugs, especially in depressed communities, he may just be accumulating statistics without actually solving anything."
Defending the crackdown yesterday, the President's spokesman Ernesto Abella said: "This is not a reckless exercise in bloodletting. (The goal) is to degrade community-based retail networks that will fuel the drug trade whoever is on top. This is a very focused effort."
