Nearly two dozen Tibetan protesters were arrested outside the United Nations building as they tried to block traffic to protest the Chinese crackdown in Tibet and demand intervention by the world body, in the third straight day of the stir.
The slogan-shouting protesters carried placards which said "UN, Where are you," "Wake up, UN," and "UN, We Need Your Support".
As the protesters carrying Tibetan flags tried to squat on the road in front of the United Nations on Monday, they were stopped by the police.
Among those arrested were two monks, one of them said to be 70-year-old.
Tsering Palden, president of New York's Tibetan Youth Congress which led the protest, said they want the UN to intervene to stop killings in Tibet by the Chinese and seek release of those arrested.
In a cautious response to the violence in Lhasa, where anti-China demonstrations erupted on Friday, UN chief Ban Ki-moon has urged Beijing to show restraint in handling the protests called on all sides avoid further confrontation.
