The lecture by Christina Toledano Åsbrink, who is resident in Israel, initially had the title "The fabricated famine in Gaza" – but after pressure from the Book Fair it was changed to "What happens to the aid to Gaza's inhabitants".
Earlier in the day, she held a lecture about the UN agency Unrwa, which initially had the title "Unrwa – the link between terror and the UN?", but was changed to "How does Unrwa work?"
A number of listeners also gathered then to mark their discontent with Toledano Åsbrink's opinions.
It is completely horrible that the Book Fair allows conspiracy theories, said a woman with a Palestinian scarf.
Nearly 70 Swedish cultural figures signed on Thursday a call against the Book Fair giving "space to genocide propaganda".
