We join the many voices in the Jewish community, including the Israeli Prime Minister, which have denounced in unison the terrorist arson attack that took the life of an Arab infant in Duma.

We also condemn the vile outpouring of Jew hatred on social media. One good example was the Facebook page of Al Jazeera presenter Mehdi Hasan. When Hasan posted a Ha’aretz article about the attack, his followers piled in with racist abuse.

One Facebook follower of Hasan, Ruksana Arik, wrote: “Why will Cameron stop when he gets funded by the Jews. He has Jewish blood in him.” Mohammed Yusuf Khatri posted: “Americans and Zionist Jews are loving it.” Mudassir Dar’s contribution read: “Jews are devil deserve hell only.” Tan Moh implored: “Oh Allah please send the worse curse ever for the Jews who are killing innocent people!” Shafiq Abbasi wrote: “Showing their true colours the terrorist Jews.” Someone going by the name of ‘Moxemedqadar Blue Moon’ commented: “I think what these settlers did was to justify why Hitler burnt them to fumes.”

In the first six months of this year, 20% of the antisemitic incidents reported in the UK were online. It is time for the social networks to proactively seek out Jew hatred on their platforms.
