The resolution, which passed by a narrow margin, mandates a comprehensive written report into the human rights situation in the country. It will focus on reports of extrajudicial killings, arbitrary arrests and enforced disappearances.

The Philippines strongly opposed the resolution and branded it a “travesty”. President Rodrigo Duterte launched the anti-narcotics campaign in 2016, to deal with a rampant drug problem.

Since then at least 6,600 dealers or users have been killed, according to police. But activists say the toll is much higher at more than 27,000. Last week, a three-year-old girl became one of the crackdown’s youngest victims after she was shot dead in a drugs raid. Police said she had been used as a human shield by her father, but the family disputes this.

Mr Duterte and his anti-narcotics campaign enjoy wide support from Filipinos. An opinion poll earlier this year gave him a 79% approval rating.
