UK joins US in Gulf mission after Iran taunts

Britain's decision to form the joint maritime task force with the US marks a departure in policy under Boris Johnson

LONDON: Britain said on Monday it will join forces with the United States to protect merchant vessels in the Gulf amid heightened tensions with Iran, after Tehran taunted Washington that its allies were too ‘ashamed’ to join the mission.

Britain's decision to form the joint maritime task force with the US marks a departure in policy under new Prime Minister Boris Johnson, after efforts under his predecessor Theresa May to form a European-led grouping.

Iran says European naval mission in Gulf would be 'provocative'

It follows a spate of incidents -- including the seizure of ships -- between Iran and Western powers, in particular Britain and the US, centred on the vital Strait of Hormuz thoroughfare.

"The UK is determined to ensure her shipping is protected from unlawful threats, and for that reason we have today joined the new maritime security mission in the Gulf," Defence Secretary Ben Wallace said in a statement.

The announcement from Britain's defence ministry did not detail which, if any, other countries would be joining the new naval coalition.

Britain was also at pains to stress that it had not changed its broader policy towards Tehran.

Iran says meeting with parties to nuclear deal 'constructive'

"We remain committed to working with Iran and our international partners to de-escalate the situation and maintain the nuclear deal," Foreign Secretary Dominic Raab said.

The announcement came hours after Iranian Foreign Minister Mohammad Javad Zarif said Washington was increasingly isolated in its hardline stance against Tehran and its allies were too "ashamed" to join its forces in the Gulf.

He also dismissed US calls for talks as a sham, confirming he had turned down an offer to meet President Donald Trump last month despite the threat of US sanctions against him.

"Today the United States is alone in the world and cannot create a coalition," he said.

"Friendly countries are too ashamed of being in a coalition with them," Zarif told a news conference, saying they had "brought this situation upon themselves, with law-breaking, by creating tensions and crises."

Tehran and Washington have been locked in a battle of nerves since last year when Trump withdrew the US from a landmark 2015 deal placing curbs on Iran's nuclear programme and began reimposing sanctions.
