TV presenter Rachel Riley has voiced her shock after seeing Londoners "partying" and "dancing" in an apparent celebration of the atrocities carried out by Hamas earlier on Saturday.
Writing on social media, she said: "Acton, half an hour ago. Popped into a cafe for some baklava with the kids and our Ukrainian friends.
"People have been brutally murdered, kidnapped and there are people in London dancing."
In another post, she wrote: "I just passed two cars in West London driving with Palestinian flags flying from each window, bouncing up and down in their cars, seemingly celebrating like they were having a party.
"Make no mistake, this is a dangerous and terrifying time for all Jews around the world."
