WIKILEAKS founder Julian Assange has denounced ''business McCarthyism'' in the US after the Bank of America halted all transactions to the website.

The Australian vowed the whistleblowing website will carry on releasing controversial leaked documents as he insisted his life is under threat.

Bank of America, the largest US bank, halted all transactions for WikiLeaks, joining other institutions that refuse to process payments for the website.

''Bank of America joins in the actions previously announced by MasterCard, PayPal, Visa Europe and others and will not process transactions of any type that we have reason to believe are intended for WikiLeaks,'' it said in a statement.
