BBC News Writes: An electronic spy network, based mainly in China, has infiltrated computers from government offices around the world, Canadian researchers say.
They said the network had infiltrated 1,295 computers in 103 countries.
They included computers belonging to foreign ministries and embassies and those linked with the Dalai Lama - Tibet's spiritual leader.
There is no conclusive evidence China's government was behind it, researchers say. Beijing also denied involvement.
