A local government official denied both accounts and said three Falun Gong followers at the camp had tried to commit suicide, but nobody had died.
The Falun Dafa Information Center said 5 female practitioners were killed and several seriously injured at Wanjia Labor Camp in Harbin, capital of Heilongjiang province, in northeastern China, around June 20.
However, a Hong Kong human rights group said on Tuesday 16 Falun Gong adherents tried to hang themselves at the camp that day after their sentences were extended for staging a hunger strike. The Information Center for Human Rights & Democracy said 10 people may have died.
Falun Gong followers overseas say the movement does not sanction killing of any sort, including suicide.
