Taking to his Truth Social platform, the US president lashed out at France, saying it did not let "planes headed to Israel, loaded up with military supplies, fly over French territory."

"We are surprised by this tweet," the French presidency said, referring to Trump's post in which he accused France of being "very unhelpful" in the US-Israeli war on Iran.

"We confirm this decision, which is consistent with France's position since the start of this conflict," the Elysee Palace said.

"France has not changed its position since day one," the presidency said.

Unlike Spain, Paris had not officially announced a ban on US aircraft involved in the conflict flying over its territory.

The French military said in early March that US military support jets had been allowed to use an air base in the south of France, adding it had "full guarantees" they were not involved in Iran strikes.
