On September 30, several mountain climbers witnessed Chinese border guards shooting at and killing Tibetan refugees trying to escape into Nepal. Of the 70 Tibetan refugees who tried to escape, at least 2 (a nun and a young boy) and possibly 7 were killed. At least 10 young children were taken into custody at gunpoint. Of the 70, 41 or so made it to Nepal.
The Chinese Government claims that the Chinese soldiers shot the Tibetans out of self defense. Check out the video that a Romanian cameraman for ProTV took of the shooting at the Tibetans and decide for yourself.
