MANILA — Since Rodrigo Duterte became president of the Philippines just over a month ago, promising to get tough on crime by having the police and the military kill drug suspects, 420 people have been killed in the campaign, according to tallies of police reports by the local news media.

Most were killed in confrontations with the police, while 154 were killed by unidentified vigilantes. This has prompted 114,833 people to turn themselves in, as either drug addicts or dealers, since Mr. Duterte took office, according to national police logs.

Addressing Congress last week in his first State of the Nation address, Mr. Duterte reiterated his take-no-prisoners approach, ordering the police to “triple” their efforts against crime.

“We will not stop until the last drug lord, the last financier and the last pusher have surrendered or been put behind bars or below the ground, if they so wish,” he said.
