France shut down the four main Israeli company stands at the Paris Airshow for refusing to remove offensive weapons from display, in a move condemned by Israel and highlighting tensions between the traditional allies, Reuters reports.

A source familiar with the matter told Reuters 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 those 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.

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.
