"The High Commissioner also deplores the repeated insults and threats of physical violence against the UN Special Rapporteur on extrajudicial, summary or arbitrary executions, Agnes Callamard, by the President of the Philippines and his supporters", Rupert Colville, spokesperson of Zeid said.
Referring specifically to Duterte's comments about Callamard, Zeid said: "This is absolutely disgraceful that the president of a country could speak in this way, using the foulest of language against a rapporteur that is highly respected".
"I'm very tempted to respond in similar language but i have chose to restrain myself opting not to respond in the same ad hominem used by the UN High Commissioner", said Roque.
Roque said Zeid, by issuing such "very harsh" language against Duterte, does not only offend the Filipino people but also insult "all countries (that) have democratically elected their heads of states".
"I will, however, state that perhaps the United Nations high commissioner's language is because of the fact that they have no democracy in his own state of Jordan".
In a statement Friday, the United Nations said the list could be considered an unacceptable attack on legitimate rights workers and activists in the Philippines, where Duterte has presided over a crackdown against suspected drug addicts and pushers that has left at least 4,000 dead.
In addition, the U.N. High Commissioner for Human Rights said Duterte should undergo a psychiatric examination.
"I will, however, state that perhaps the UN High Commissioner's language is because of the fact that they have no democracy in his own state of Jordan".
The petition included Victoria Tauli-Corpuz, appointed in 2014 as United Nations special rapporteur on the rights of indigenous peoples, who was listed as a senior member of a Maoist rebel group.
Roque said he hopes even if Jordan does not have the same democratic system as the Philippines, the Arab the will respect the Philippines' democratic system.
He also defended the inclusion of Victoria Tauli-Corpuz on the list of 600 Communists submitted to a Manila court, insisting that everyone on the list was suspected of "membership in or association with the Communist Party of the Philippines-New People's Army [NPA] as reported over the years", and they would have a chance to prove otherwise in court.
According to Zeid, the Philippine justice ministry charged Carpuz in a regional court last month with terrorism.
According to her colleagues, the accusations came after her public criticism of killings and attacks on the Lumad people by members of the Philippine armed forces in Mindanao.
"Government accusations that worldwide human rights experts have links to the NPA seek to undermine the valuable work they do to promote accountability for rights abuses", Asia division researcher for HRW Carlos Conde said in a statement. This move, therefore, only reinforces the classification that the CPP-NPA is a terrorist group,"Roque said Saturday afternoon".
"The DOJ would have not filed a petition without evidence that she is a member of, or somehow affiliated with the CPP-NPA", he added.
This "terrorist tag further worsens the fragile state of indigenous peoples" human rights in the country.
