Two major cultural sites in Paris, including the Louvre, are being accused of discriminating against Israeli visitors.
Last month, a professor of art history at Tel Aviv University, Sefy Hendler, tried to book a guided tour for a group of 12 students at the Louvre and Sainte-Chapelle, a medieval chapel, for later this month.
The professor told reporters he had been turned down by both the museum and the chapel, despite the fact that he had tried booking on different dates.
Several days later, Mr Hendler tried to reserve slots under the name of made-up Italian and Emirati art history institutes, and was accepted immediately.
