Antisemtism is being used to undermine Israel, Israeli Foreign Minister Avigdor Lieberman has warned.

“Classic antisemitism, along with Iranian funding and Islamic antisemitism, is being used to incite hatred against Jews, and to delegitimise the state of Israel,” he told the Foreign Ministry’s third annual Global Forum for Combating Antisemitism.

“The people behind the assault against Israel have crossed the line. They seek to destroy the Jewish state and take away the right of the Jewish people to define themselves.

“Instead of saying ‘throw the Jews into the sea’, they talk of a world without Zionism, and without Israel.”

Mr Lieberman blasted Britain for allowing an arrest warrant for opposition leader Tzipi Livni to be issued, and joked that it would soon issue warrants for Nato forces in Afghanistan.

“It is in Britain’s interest, not Israel’s, to make a change,” he said.

More than 500 people attended the international conference.
