President Rodrigo Duterte said on Friday his counterparts in East Asian Summit, including United States President Barack Obama, were silenced when he lectured them on human rights violations.

In a speech before the Filipino community in Jakarta, Duterte said that during the East Asia Summit interaction in Laos, he showed photos of Filipino Muslims killed by the Americans during their pacification campaign.

"I said, 'since human rights was mentioned', I produced a few pages with pictures in the pacification campaign by the Americans at the run of century...almost 600,000 Muslims, 6,000 were murdered. They were just buried in a common pit," he said.

He said he told them:"What do you intend to do? Do not tell me that is water under the bridge."

"A human rights violation whether committed by Moses or Abraham is still a violation of human rights. When was this philosophy about the human dignity and the human rights evolved? Now or during this time? They were silent," Duterte said.

Duterte said United Nations Secretary General Ban Ki-Moon also mentioned human rights violations in passing, which he described as "an illegitimate statement."

Duterte's intervention was not part of his actual speech prepared by the Department of Foreign Affairs.

The UN, US and other groups have been criticizing the Duterte administration for the alleged extrajudicial killings of drug suspects in the Philippines and which number already reached to about 3,000.

Duterte has declared an all-out war against illegal drugs.

Duterte also said during his brief encounter with Obama, he told him that he never called him a "son of a bitch."

He said his press conference at the Davao City airport prior to his departure for Laos would show that he never said that.

Obama cancelled his bilateral meeting with Duterte at the sidelines of the ASEAN Summit and Related Summits in Vientiane after the Philippine president's expletives against him. Celerina Monte/DMS
