Google threatens to quit China, saying it could no longer tolerate what it calls strict censorship.
Google says that accounts of dozens of rights activists in China, the US and Europe were being routinely accessed by outsiders.
Google did not state who was behind it - but said they had "security and human rights implications" for what it called the "global debate about freedom of speech".
Google launched in China in 2006. It did agree to some censorship, as required by the Chinese government.
Is this a case of a company putting ethics above business? Will Google leave such a huge market? And what are the potential costs of such a move?
