Two Tibetan monks set themselves on fire outside a temple in Lhasa to protest against Chinese rule, according to a report.
US-based Radio Free Asia said in a statement that the men were taken away by authorities within minutes of setting themselves on fire outside the Jokhang Temple on Sunday.
The US broadcaster cited a Tibetan living in exile as saying he had heard from others inside Tibet that flames had engulfed the two men and that they were believed to be seriously hurt or dead, The Guardian reports.
Meanwhile, a woman with the Lhasa city police denied any immolation attempts had occurred.
Fu Jun, an official with the propaganda department of the Tibetan regional Communist party office, also said he was unaware of any immolations.
According to the paper, nearly 34 such protests since March 2011 have drawn attention to China’s political and religious restrictions on Tibetans.
Most self-immolations have taken place in heavily Tibetan areas of China. Only one had occurred in Tibet itself.
