French exhibition authorities have blocked access to Israeli defence industry displays at the Paris Air Show on June 16, prompting strong condemnation from Israeli officials as "outrageous" discrimination following its attacks on Iran and Gaza, LCI reported.

France, unlike the United States and the United Kingdom a day earlier on June 15 remained on the fence whether it would support Israel in its attacks on Iran, which began on June 13, which Israel said was a pre-emptive strike on nuclear research centres.

Black barriers were erected around five Israeli defence companies' stands at Le Bourget airfield following concerns the exhibits featured "offensive weapons" potentially used in Gaza operations, according to a French government source.

The affected companies are Israel Aerospace Industries, Rafael Uvision, Elbit and Aeronautics, all manufacturers of drones, guided bombs and missiles which are believed to be currently used in both Gaza and Iran.

Speaking from Jerusalem Israel’s President Isaac Herzog described the French organisers decision as creating an "Israeli ghetto" and demanded immediate correction of the situation during an appearance on French television channel LCI.

"Israeli companies have signed contracts with the organisers," Herzog said, expressing shock at what he termed the "outrageous" decision.

The Israeli Defence Ministry accused France of hiding behind political considerations to exclude Israeli weapons that compete with French industries, particularly noting Israeli technologies' "impressive and precise performance in Iran."

An Israeli exhibitor wrote in yellow chalk on one barrier that the concealed defence systems "are protecting the state of Israel these days" whilst alleging French discrimination.

The controversy overshadowed the major aerospace industry gathering, which typically focuses on aircraft displays and major orders for manufacturers, including Airbus and Boeing.

Local lawmakers from Seine-Saint-Denis department boycotted French Prime Minister François Bayrou's opening visit in protest over Israeli participation.

"Never has the world been so disrupted and destabilised," Bayrou said during a roundtable event, urging nations to tackle challenges "together, not against each other."

Earlier, Gila Gamlil, Israeli cabinet member said "We firmly call on the United States to join the war against Iran" as the two countries continue to attack each others' infrastructure. .
