Lhasa, June 1 (ANI): Chinese security forces have reportedly launched a wave of detentions in Lhasa following two self-immolations in the Tibetan capital.

Witnesses to the immolations had been arrested and Tibetans from outside Lhasa sent home, the BBC reports.

US broadcaster Radio Free Asia, citing unidentified sources, revealed that an estimated 600 Tibetans had been rounded up in Lhasa since the incident on Sunday.

Two Tibetan men had set themselves on fire outside the Jokhang temple in an apparent protest against China's religious and political suppression.

There have been several such incidents in Tibetan areas outside Tibet, but these were the first in Lhasa.

One of the men died while the other 'survived with injuries', China's state run media reported. (ANI)
