The footage of the nun burning was obtained by Students for a Free Tibet that purportedly shows the images of 35-year-old Palden Choetso setting herself on fire. Her death was earlier reported on Nov 3 from Ganzi prefecture in Sichuan province that is mostly inhabited by Tibetans.
The video shows a woman in nun's robes standing on a street engulfed in fire.
The video also shows close to 10,000 mourners gathered at a monastery to pay their respects to the nun. They held a candlelight vigil with another 1,000 monks and nuns holding prayers inside the monastery.
As many as 11 monks, nuns, and former monks have indulged in self-immolation to register their protest against the repressive Chinese aggression in the place.
