Unidentified hackers brought down several public NATO websites with cyber attacks on Saturday, the alliance said, in what appeared the latest escalation in cyberspace over growing tensions over Crimea. A group calling itself "cyber berkut" said the attack had been carried out by patriotic Ukrainians angry over what they saw as NATO interference in their country.
The claim, made at www.cyber-berkut.org, could not immediately be independently verified. Cyber berkut is a reference to the feared and since disbanded riot squads used by the government of ousted pro-Russian Ukrainian President Viktor Yanukovich. (AP)
