Troops wearing ski masks and carrying machine guns rappelled to its deck from a helicopter, the same tactics used by British Royal Marines to seize an Iranian tanker off the coast of Gibraltar two weeks ago.Friday's action in the global oil trade's most important waterway has been viewed in the West as a major escalation after three months of confrontation that has already taken Iran and the United States to the brink of war.It follows weeks of threats from Tehran to retaliate for Britain's seizure of the Iranian tanker Grace 1, accused of violating sanctions on Syria.British Defence Secretary Penny Mordaunt called the incident a "hostile act." Foreign Secretary Jeremy Hunt said he had expressed "extreme disappointment" by phone to his Iranian counterpart, Mohammad Javad Zarif. Britain also summoned the Iranian charge d'affaires in London.A spokesman for Iran's Revolutionary Guards, Brigadier-General Ramezan Sharif, said Tehran had seized the ship in the Strait of Hormuz despite the "resistance and interference" of a British warship which had been escorting it. No British warship was visible in the video posted by the Guards.Iran's Fars news agency said the Guards had taken control of the Stena Impero on Friday after it collided with an Iranian fishing boat whose distress call it ignored.The vessel, carrying no cargo, was taken to the Iranian port of Bandar Abbas. It would remain there with its 23 crew -- 18 of them Indians -- while the accident was investigated, Iranian news agencies quoted the head of Ports and Maritime Organisation in southern Hormozgan province, Allahmorad Afifipour, as saying.Zarif told Britain's Hunt that the ship must go through a legal process before it could be released, Iran's ISNA news agency reported.The strait, between Iran and the Arabian peninsula, is the sole outlet for exports of most Middle Eastern oil, and the seizure sent oil prices sharply higher. The United States, which tightened sanctions against Iran in May with the aim of halting its oil exports altogether, has been warning for months of an Iranian threat to shipping in the strait.Another oil tanker, the Mesdar, was also boarded by Iranian personnel on Friday and temporarily forced to divert towards Iran, but later was allowed to continue on its route through the strait. On Saturday Algeria's APS news agency said the Mesdar was owned by Algeria's state oil company Sonatrach.France, Germany and the European Union joined Britain in condemning the seizure.The three big European countries are signatories to a 2015 nuclear deal between Tehran and world powers that Washington undermined by quitting last year, setting Iran's already fragile relations with the West on a downward spiral.Under the pact, Iran agreed to restrict nuclear work in return for lifting sanctions. The European countries opposed the Trump administration's decision to abandon the agreement last year, but have so far failed to fulfill promises to Iran of providing alternative means for it to access world trade.EXTREME DISAPPOINTMENT"Just spoke to ... Zarif and expressed extreme disappointment that having assured me last Saturday Iran wanted to de-escalate situation, they have behaved in the opposite way," tweeted British Foreign Secretary Hunt. "This has to be about actions not words if we are to find a way through."Earlier he said London's reaction would be "considered but robust," and it would ensure the safety of its shipping.On Friday, Hunt said the solution would be found via diplomacy and London was "not looking at military options." Britain's government said it had advised British shipping to stay out of the Hormuz area for an interim period.The past three months of escalation have seen the United States and Iran come as close as ever to direct armed conflict. In June, Tehran shot down a U.S. drone and Trump ordered retaliatory air strikes, only to call them off just minutes before impact.In New Delhi, India's foreign ministry said it was actively seeking the release of its nationals among the crew.Operator Stena Bulk said on Friday the tanker had been "in full compliance with all navigation and international regulations." On Saturday it said it was preparing a request to visit the crew.The vessel had been heading to a port in Saudi Arabia and suddenly changed course after passing through the strait.The United States has blamed Iran for a series of attacks on shipping around the Strait of Hormuz. Tehran rejects the allegations. Washington also said it had this week downed an Iranian drone near where the Stena Impero was seized.The United States is sending military personnel and resources to Saudi Arabia for the first time since the U.S. invasion of Iraq in 2003.#Iran’s Revolutionary Guard operatives capture the #UK-flagged tanker #StenaImperohttps://t.co/w3Q2GYAJax pic.twitter.com/49OHBJsZnw

Blue and White chairman Benny Gantz responded to the incident and said Iran and its proxies are testing the world's patience.
"Whoever ignores today's threats may soon face a far graver, more destructive reality," he said. "As for Nasrallah and his threats, he knows all too well that any threat to Israel will be met with a very severe response. I'd like to remind him what happened when he attempted to threaten us over a decade ago.
Nasrallah should know that this time around he won't make it back to the bunker."
MK Yair Lapid, Blue and White's number two candidate, said the seizure of the British tanker proves that Europe should have joined US President Donald Trump in cancelling the Iranian nuclear deal and increasing the sanctions on the Iranian regime.
"The world must present Iran with a clear choice: end your nuclear program and your support for terror worldwide or we will dismantle your economy,” Lapid wrote on Twitter.Gil Hoffman contributed to this report.
