Myanmar's extremist Buddhist monk Wirathu called the United Nations' special envoy for human rights in Burma a "whore" during a public address in Yangon.
Leader of the controversial 969 nationalist movement, Wirathu was hitting back at Yanghee Lee, special rapporteur on Myanmar, for her comments in defence of Rohingya Muslims.
Wirathu, who has already served a nine-year jail term for inciting anti-Muslim prejudice, belongs to the group of nationalists that believe that Rohingya Muslims are unwelcome migrants from Bangladesh.
Having been tagged as "one of the world's most persecuted minorities", the Rohingya Muslims continue to be victims of human rights violations under the Burmese government since 1978.
In a video that has been translated by the Democratic Voice of Burma and made public, Wirathu calls Lee a "bitch" for expressing human rights concerns over the Race Protection Laws.
"We have already made public our Race Protection Law, but without even studying it, this bitch [kaungma in Burmese] keeps on complaining about how it is against human rights!" said Wirathu.
"Can this whore really be from a respectable family background?" the extremist Buddhist asked the crowd, which promptly replied "No!"
"Don't assume you are a respectable person, just because you have a position in the UN," the monk went on. "In our country, you are just a whore. You may offer your a**e to the kalars [derogatory term for Muslims] but you will never sell off our Rakhine state."
The UN has not yet made any response to the hateful speech.
However, many including some Buddhist monks have commented on Wirathu's foul language.
Derek Ty, for example, said, "I'm a Burmese Buddhist. I definitely condemn this monk's hate speech. It doesn't solve the current issue and only increases animosity. This monk should be stripped of his monk hood for inciting hates and possible violence. He makes Buddhism looks bad."
Meanwhile, Myat Phyo Thu said, "An UNEDUCATED monk and MORE UNEDUCATED SUPPORTERS."
YouTube user tjr22446688 fears whether these Buddhists would become the next ISIS. "I am extremely sad to hear that such a Myanmar Buddhist monk talked in public. Very much disgraceful and such a shame. I hope he and his follower will not become extremist like Buddhist ISIS," he posted.
