US Navy to blockade Strait of Hormuz ‘effective immediately,’ Trump says

President Donald Trump said on Sunday the U.S. Navy would immediately start blockading the Strait of Hormuz , raising the stakes after marathon talks with Iran failed to reach a deal to end the war , jeopardizing a fragile two-week ceasefire.

Trump also said in a post on Truth Social that the U.S. would interdict every vessel in international waters that had paid a toll to Iran, and begin destroying mines that he said the Iranians had dropped in the strait, a choke point for about 20% of global energy supplies that Iran has blocked.

“Effective immediately, the United States Navy , the Finest in the World, will begin the process of BLOCKADING any and all Ships trying to enter, or leave, the Strait of Hormuz,” he said.

“I have also instructed our Navy to seek and interdict every vessel in International Waters that has paid a toll to Iran. No one who pays an illegal toll will have safe passage on the high seas,” Trump added.

“Any Iranian who fires at us, or at peaceful vessels, will be BLOWN TO HELL!” he added.

Each side had earlier blamed the other for the failure of talks to end six weeks of fighting that has killed thousands, roiled the global economy and sent oil prices soaring.

“The bad news is that we have not reached an agreement, and I think that’s bad news for Iran much more than it’s bad news for the United States of America,” Vice President JD Vance, the head of the U.S. delegation at the weekend talks, said earlier.

“We’ve made very clear what our red lines are,” Vance added.

Iran’s Parliamentary Speaker Mohammad Baqer Qalibaf, who led his country’s delegation along with Foreign Minister Abbas Araqchi, blamed the U.S. for not winning Tehran’s trust despite his team offering “forward-looking initiatives.”

“The U.S. has understood Iran’s logic and principles and it’s time for them to decide whether they can earn our trust or not,” Qalibaf said on X.

The talks, after a ceasefire earlier in the week, were the first direct U.S.-Iranian meeting in more than a decade and the highest-level discussions since the 1979 Islamic Revolution.

Vance said Iran had chosen not to accept American terms, including not to build nuclear weapons.

“I could go into great detail, and talk about much that has been gotten but, there is only one thing that matters — IRAN IS UNWILLING TO GIVE UP ITS NUCLEAR AMBITIONS!” Trump said later.

Iran’s semi-official Tasnim news agency said “excessive” U.S. demands had hindered reaching a deal. Other Iranian media said there was agreement on a number of issues, but the Strait of Hormuz and Iran’s nuclear program were the main points of difference.

Pakistan’s Foreign Minister Ishaq Dar said it was “imperative” to preserve the ceasefire that was agreed last Tuesday as the sides attempt to wind down a war that began on February 28 with air strikes by the U.S. and Israel on Iran.

Israeli security cabinet minister Zeev Elkin told Army Radio that more talks were still an option, but added: “The Iranians are playing with fire.”

In a brief press conference, Vance did not mention reopening the Strait of Hormuz.

Even as the talks took place, U.S. ally Israel continued bombing Tehran-backed Hezbollah militants in Lebanon, insisting that that conflict was not part of the Iran-U.S. ceasefire. Iran says the fighting in Lebanon must stop.

The Israeli military said it struck Hezbollah rocket launchers overnight into Sunday and black smoke could be seen rising in the southern suburbs of the Lebanese capital Beirut on Sunday. In Israeli villages near the border, air raid sirens sounded, warning of incoming rocket fire from Lebanon.

Tehran is demanding control of the Strait of Hormuz, payment of war reparations and a ceasefire across the region, including in Lebanon, according to Iranian state TV and officials, as well as the release of its frozen assets abroad.

Tehran also wants to collect transit fees in the Strait of Hormuz.

Despite the differences in Islamabad, three supertankers fully laden with oil passed through the Strait of Hormuz on Saturday, shipping data showed, in what appeared to be the first vessels to exit the Gulf since the ceasefire deal.

Hundreds of tankers are still stuck in the Gulf, waiting to exit during the two-week ceasefire period.

Trump’s stated goals have shifted, but as a minimum he wants free passage for global shipping through the strait and the crippling of Iran’s nuclear enrichment program to ensure it cannot produce an atomic bomb.

Tehran has long denied seeking to build a nuclear weapon.

美国总统唐纳德·特朗普周日表示，美国海军将立即开始封锁霍尔木兹海峡。此前，与伊朗的马拉松式谈判未能达成结束战争的协议，这使得脆弱的两周停火协议岌岌可危，也加剧了局势的紧张。

特朗普还在 Truth Social 上发帖称，美国将拦截所有在国际水域向伊朗支付过路费的船只，并开始摧毁他所说的伊朗人在霍尔木兹海峡投放的水雷。霍尔木兹海峡是全球约 20% 能源供应的咽喉要道，伊朗一直封锁着这条海峡。

“即日起，世界上最优秀的美国海军将开始封锁任何试图进入或离开霍尔木兹海峡的船只，”他说。

特朗普补充说：“我还指示海军在国际水域搜寻并拦截所有向伊朗缴纳过路费的船只。任何非法缴纳过路费的人都无法在公海上安全通行。”

“任何向我们或和平船只开火的伊朗人，都将被炸得粉身碎骨！”他补充道。

此前双方都指责对方导致旨在结束持续六周冲突的谈判失败，这场冲突已造成数千人死亡，扰乱了全球经济，并导致油价飙升。

“坏消息是我们还没有达成协议，我认为这对伊朗来说比对美国来说更糟糕，”美国副总统、周末会谈美国代表团团长万斯早些时候表示。

“我们已经非常明确地表明了我们的底线，”万斯补充道。

伊朗议会议长穆罕默德·巴格尔·卡利巴夫率领伊朗代表团与外交部长阿巴斯·阿拉格奇一同访问美国，他指责美国未能赢得德黑兰的信任，尽管他的团队提出了“具有前瞻性的倡议”。

“美国已经了解了伊朗的逻辑和原则，现在是他们决定能否赢得我们信任的时候了，”卡利巴夫在X上说道。

本周早些时候达成停火协议后举行的会谈，是十多年来美伊之间的首次直接会晤，也是自 1979 年伊斯兰革命以来最高级别的会谈。

万斯表示，伊朗选择不接受美国的条件，包括不制造核武器。

“我可以详细阐述，谈谈我们已经取得的很多进展，但是，只有一件事最重要——伊朗不愿放弃其核野心！”特朗普后来说道。

伊朗半官方的塔斯尼姆通讯社称，美国“过分”的要求阻碍了协议的达成。其他伊朗媒体则表示，双方在一些问题上达成了一致，但霍尔木兹海峡和伊朗核计划是主要分歧点。

巴基斯坦外交部长伊沙克·达尔表示，双方试图结束这场始于2月28日美国和以色列对伊朗发动空袭的战争，因此维护上周二达成的停火协议“至关重要”。

以色列安全内阁部长泽夫·埃尔金在接受以色列陆军电台采访时表示，继续谈判仍然是一个选项，但他补充说：“伊朗人是在玩火。”

在一次简短的新闻发布会上，万斯没有提及重新开放霍尔木兹海峡。

就在会谈进行的同时，美国的盟友以色列继续轰炸黎巴嫩境内受伊朗支持的真主党武装分子，并坚称这场冲突不属于伊朗与美国停火协议的范畴。伊朗则表示，黎巴嫩的战斗必须停止。

以色列军方称，周日凌晨对真主党火箭发射阵地发动了袭击，周日黎巴嫩首都贝鲁特南部郊区升起了滚滚黑烟。以色列边境附近的村庄拉响了空袭警报，警告黎巴嫩方面可能发动火箭弹袭击。

据伊朗国家电视台和官员称，德黑兰要求控制霍尔木兹海峡，支付战争赔款，并在包括黎巴嫩在内的整个地区实现停火，同时还要求解冻其在海外被冻结的资产。

德黑兰还想收取霍尔木兹海峡的过境费。

尽管伊斯兰堡方面存在分歧，但航运数据显示，周六有三艘满载石油的超级油轮通过了霍尔木兹海峡，这似乎是自停火协议达成以来首批离开海湾的船只。

数百艘油轮仍滞留在海湾，等待在为期两周的停火期内离开。

特朗普的既定目标已经发生了变化，但他至少希望全球航运能够自由通过海峡，并削弱伊朗的核浓缩计划，以确保其无法制造原子弹。

德黑兰一直否认寻求制造核武器。
