Tibetan self-immolation

A woman and a monk have set themselves on fire in separate protests against the Chinese occupation of Tibet.

The 26-year-old woman, Dolkar Kyi, died at a monastery in a Tibetan area of China, according to the London-based advocacy group Free Tibet.

The group said it received two photographs of the body, which remains at the Tso Monastery in the Amdo region, part of eastern occupied Tibet.

The pictures show Dolkar lying on the ground with her hands clasped in prayer.

Witnesses said that bystanders tried to douse the fire but Dolkar died of her injuries.

The man, identified as 21-year-old monk Lobsang Tsultrim from Kirti Monastery, survived after setting himself on fire in southwestern China's Sichuan province.

Security personnel quickly extinguished the flames and took the man away in a security vehicle, Free Tibet said. His upper body was badly burned.

More than 40 people across Tibet have tried to burn themselves to death in recent months in protest against the government. Most of the martyrs are monks from Kirti Monastery.

"As the world's media focuses on the discipline of Chinese athletes, Chinese state repression is driving Tibetans to set fire to themselves under a media blackout," said Free Tibet director Stephanie Brigden.

"China is competing in the Olympic Games despite having broken every commitment on human rights made during its bid for the 2008 Games."

In May, hundreds of Tibetans were arrested in Lhasa, the administrative capital of Tibet, by Chinese security officers following a fresh wave of incidents.

A mother of three burned herself to death as Tibetans from across China flocked to Lhasa to mark the Buddhist month Saka Dawa, which commemorates the birth, enlightenment and death of Buddha.

In June, footage of two Tibetan men engulfed in flames while holding up Tibetan flags and calling for independence went viral.
