A Tibetan mother of four killed herself by self-immolation on Sunday to protest Chinese rule, according to a report on Monday by Radio Free Asia, which is financed by the United States government. The report said Kalkyi, 30, set fire to herself near a monastery in the county of Dzamthang in Ngaba Prefecture, which has been a focal point of the wave of Tibetan self-immolations that began in 2009. At least 110 people in Tibetan regions of China have set fire to themselves, and the vast majority have died. Ms. Kalkyi’s self-immolation took place around 3:30 p.m. Sunday, and her body was taken by locals to the Jonang monastery, according to Radio Free Asia, which cited sources inside Tibet. Ms. Kalkyi had three sons and one daughter, all under the age of 15. Radio Free Asia said that Ms. Kalkyi was the 16th woman to self-immolate since 2009. On March 13, a woman, Konchog Wangmo, 31, killed herself by self-immolation in Ngaba Prefecture, and her husband, Drolma Kyab, was later detained by the authorities, the news service reported.
