President Emmanuel Macron has said that France “never envisaged” a naval deployment in the Strait of Hormuz but rather a security mission that would be “coordinated with Iran”.

At a news conference in Nairobi, Macron said he was sticking to his position opposing a blockade from either side, and to “reject any toll” to ensure ships are able to pass through the strategic waterway.

Iran on Sunday warned of a “decisive and immediate response” to any French or British deployments in the strait, after both announced they would send military vessels to the region.

“There was never any question of a deployment but we are ready,” said Macron.

“We have put together an ad hoc mission, co-led with the British, which has brought together 50 countries and international organisations to enable, in a coordinated way with Iran and by deconflicting the situation with all the countries of the region and the United States, the resumption of maritime traffic as soon as conditions allow,” he added.
