RIYADH, Saudi Arabia, Jan. 9 (UPI) -- Banks in Saudi Arabia began implementing tight security measures after Israel threatened to retaliate against a credit card attack by a Saudi hacker.
Israeli Deputy Foreign Minister Danny Ayalon compared the hacking -- which exposed credit card information of thousands of Israeli card-holders -- to a terrorist operation and vowed that no Saudi entity would be exempt from any retaliation by Israel, al-Arabiya reported Monday.
