The New York-based group, Human Rights Watch, said Tuesday that both men's medical condition is very serious and they should be released immediately.
Human Rights Watch says the two prisoners (identified as Tserang Dondrup and Tashi Phuntsog) were detained more than a year ago in connection with the case of a locally renowned monk. That monk (Tenzin Delek) was charged (along with another man) with planning an April 2002 bomb blast in the southwestern city of Chengdu that wounded several people.
The human rights group says the conditions of both prisoners have seriously deteriorated since their imprisonment. A spokesman for the group called on the Chinese government to release information about their current medical condition and the charges against them.
