Obama scraps planned talks with Duterte over 'son of whore' slur

The pair had been due to hold a bilateral meeting on the sidelines of a gathering of global leaders in the Laos capital Vientiane.

Mr Duterte had bristled at warnings he would face questioning by Mr Obama over a war against drugs in the Philippines that has claimed more than 2,400 lives in just over two months.

Police say about 900 of those killed died in police operations, and the rest were "deaths under investigation", a term human rights activists say is a euphemism for vigilante and extrajudicial killings.

Mr Duterte said he might ask China and African nations to form another body. He also accused the UN of failing on terrorism, hunger and ending conflicts.

Mr Duterte, elected in May, has sanctioned the killing of traffickers to try to wipe out the drugs trade.

The UN has repeatedly condemned the drive as a violation of human rights.

Some 900 suspected drug traffickers have been killed since Mr Duterte was elected on 9 May.

The controversial former mayor of Davao City, 71, overthrew the political establishment, promising a "bloody war" on crime and action on corruption.

In his inaugural speech he promised to make sweeping changes to the country's political system.

"I see the erosion of the people's trust in their country's leaders," he said.

"The erosion of faith in our judicial system. The erosion of confidence in the capacity of our public servants to make the people's lives better, safer and healthier."

Philippine police shoot dead drug suspects, raising fears over president-elect's rule

Gunmen on motorcycles also murdered three petty criminals in Mr Duterte's hometown of Davao, police said, deepening fears of mass extra-judicial killings once the controversial politician begins his six-year term on June 30.

Police insisted the eight drug suspects were killed lawfully, with the officers only firing back after being shot at in three separate raids.

One occurred in Manila, another near the capital, and the third in a small town in the northern Philippines.
