A full-page advertisement has been taken out in the Washington Post calling Kiwi musician Lorde a bigot and accusing New Zealand of prejudice against Israel.

The ad on the fifth page of the paper's December 31 edition - taken out by outspoken rabbi Shmuley Boteach's This World: The Values Network - criticises the 21-year-old for joining "a global anti-semitic boycott of Israel" but still performing in Russia.

It features a large photo of the singer superimposed over a picture of men running through rubble cradling babies with the headline "Lorde and New Zealand ignore Syria to attack Israel".

The Grammy winner this month cancelled a concert scheduled in Tel Aviv for June after criticism from activists in the Boycott, Divestment, Sanctions movement.
