NEW: President Rodrigo Duterte promises to continue fight against drugs

Top police officer says 300 officers linked to drug trade, will be tried in court

Manila, Philippines CNN  — 

Philippines President Rodrigo Duterte vows there will be no letup in his hard-line crackdown on drugs and related crime despite global concerns over the alarming death toll and possible human rights violations.

More than 1,800 people have died in police-related killings and unsolved slayings often attributed to vigilantes since Duterte took office in late June, according to police statistics.

On Tuesday, Duterte promised to fight the drug problem “tooth and nail.”

“The fight against drugs will continue to the last day of my term,” Duterte said at Malacañang Palace. “The fight against corruption will continue for six years maybe. … Many will be unhappy, but I think the bigger picture is that I would have something to live by for my country.”
