The Guardian has published a wildly inaccurate and inflammatory advert from supporters of the Israeli state branding the Palestinian resistance as ‘child killers’. Activists respond

We write to condemn the Guardian’s decision to print a wildly inaccurate and inflammatory advert from supporters of the state of Israel branding the Palestinian resistance as ‘child killers’. This is especially sickening when Israel’s latest bombardment of Gaza has killed close to 400 Palestinian children. Amnesty International has condemned the deliberate targeting of schools and hospitals by Israel as a war crime.

Among the advert’s very many inaccuracies is the claim that those forces opposing Israel do not have the support of Palestinians when the current Israeli offensive is against a united Hamas-Fatah government which commands the support of the majority of Palestinians.

Sadly the decision to print this advert, rejected by The Times newspaper, is another sign of the increasingly pro-Israeli bias of the Guardian’s editorial policy, including the gross underestimate of the size of last Saturday’s Gaza protest demonstration. You are repeatedly running the slur that those who campaign in support of Palestine are anti-Semitic when the very many Jews in the movement and the movement as a whole have repeatedly made it absolutely clear that this is not the case.

We call on the editor to redress the balance in future coverage.
