A source familiar with the matter told Reuters on Monday that the instruction came from French authorities after Israeli firms failed to comply with a direction from a French security agency to remove offensive or kinetic weapons from the stands.
The stands were being used by Elbit Systems , Rafael, IAI and Uvision. Three smaller Israeli stands, which didn't have hardware on display, and an Israeli Ministry of Defence stand, remain open.
France, a long-time Israeli ally, has gradually hardened its position on the government of Benjamin Netanyahu over its actions in Gaza and military interventions abroad.
French President Emmanuel Macron made a distinction last week between Israel's right to protect itself, which France supports and could take part in, and strikes on Iran it did not recommend.
Israel's defence ministry said it had categorically rejected the order to remove some weapons systems from displays, and that exhibition organisers responded by erecting a black wall that separated the Israeli industry pavilions from others.
This action, it added, was carried out in the middle of the night after Israeli defence officials and companies had already finished setting up their displays.
"This outrageous and unprecedented decision reeks of policy-driven and commercial considerations," the ministry said in a statement.
Rafael described the French move as "unprecedented, unjustified, and politically motivated," adding it fully supported the Israeli ministry of defence's decision not to comply with the order to remove some equipment from display.
