A rights group is calling on China to release two Tibetan journalists who were arrested after they wrote about the March 2008 protests in Tibet.
Paris-based Reporters Without Borders says Buddha and Kalsang Jinpa wrote for and edited the Tibetan-language magazine Shar Dhung-Ri.
The group says Buddha was arrested in June and Kalsang Jinpa in July, both in the city of Xining in Qinghai province. They were accused of "separatism."
China has not commented on the arrests.
Reporters Without Borders says their arrests bring the total of Tibetan journalists in Chinese detention to 15. It says at least another 50 Tibetans are being held for sending information out of the country.
The group says the arrests are drastically curtailing the ability of Tibetan intellectuals to make their voices heard.
The Chinese government sent troops into Tibet on March 14, 2008, to break up what began as peaceful protests by monks from monasteries and and around the Tibetan capital, Lhasa. China says it was forced to act because government buildings and shops were being vandalized.
