Media magnate Rupert Murdoch stirred an online row with a tweet complaining about the "Jewish owned" press and apologized again in a bid to calm the furor.
Murdoch, whose News Corporation empire includes HarperCollins publishers, Fox television, BSkyB, The Wall Street Journal and the London Times, wrote Saturday on Twitter: "Why is Jewish owned press so consistently anti-Israel in every crisis?"
Facing accusations of anti-Semitism, Murdoch backtracked on Sunday, saying he disagreed with his critics, but was sorry anyway.
"'Jewish owned press' have been sternly criticised, suggesting link to Jewish reporters. Don't see this, but apologize unreservedly," Murdoch, who is known as a strong Israel supporter, said in a new tweet.
