A row has broken out between Wikileaks and one of the newspapers it collaborated with to leak US diplomatic cables. The whistle-blowing group said unredacted versions of the 251,000 diplomatic cables had been leaked on the internet. Wikileaks blamed the disclosure on the Guardian newspaper and said it had started legal action against the paper. The newspaper has strongly denied the claims, blaming a "security breach". In a short statement on Twitter, Wikileaks said: "A Guardian journalist has, in a previously undetected act of gross negligence or malice... disclosed top secret decryption passwords to the entire, unredacted, Wikileaks Cablegate archive.
