Berliner Tageblatt - US military to begin blockade of Iranian ports on Monday

Trump had announced on social media he would blockade the strategic Strait of Hormuz trading route that he has been demanding Tehran fully re-open, after his vice president, JD Vance left negotiations with an Iranian delegation in Islamabad on Sunday.

The stall in talks dashed global hopes of a deal to permanently end the war that has killed thousands and thrown the global economy into turmoil since it began in late February.

As negotiating teams flew out, mediator Pakistan said it would keep facilitating their dialogue and has called on both sides to honour the fragile two-week ceasefire struck last week that experts said could be put at risk by any maritime military blockade.

"The blockade will be enforced impartially against vessels of all nations entering or departing Iranian ports and coastal areas, including all Iranian ports on the Arabian Gulf and Gulf of Oman," US Central Command said in a statement, adding it would begin at 1400 GMT on Monday.

US forces would not impede vessels transiting the Strait of Hormuz to and from non-Iranian ports, it added.

Trump on his Truth Social platform confirmed the US military's statement, a more limited operation than envisaged in his earlier post that asserted all ships trying to enter or exit the strait would be blocked.

Iran's Revolutionary Guards had warned before the US military announcement that they had full control of traffic through Hormuz and would trap any challenger "in a deadly vortex".

In his lengthy social media post, Trump said on Sunday his goal was to clear the strait of mines and reopen it to all shipping, but that Iran must not be allowed to profit from controlling the waterway.

"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," Trump said. "Any Iranian who fires at us, or at peaceful vessels, will be BLOWN TO HELL!"

Oil prices -- which tumbled last week after the temporary ceasefire -- jumped around eight percent Monday, with both key WTI and Brent contracts topping $100 a barrel.

Iran's parliament speaker Mohammad Bagher Ghalibaf, who led Tehran's delegation in Pakistan, said Tehran would "not bow to any threats" from Washington, while navy chief Shahram Irani called Trump's blockade threat "ridiculous".

After the highest-level US-Iran talks since the 1979 Islamic Revolution failed to deliver a deal, Iranian foreign ministry Abbas Araghchi blamed "maximalism, shifting goalposts, and (a) blockade" that prevented an agreement he said they were "just inches away from".

Trump told reporters on Sunday he was ambivalent on the prospect of talks continuing with Iran.

"I don't care if they come back or not. If they don't come back, I'm fine," he said.

- 'Final and best offer' -

Tehran has already been restricting traffic through the strait -- a key route for global oil and gas shipments -- while allowing some vessels serving friendly countries such as China to pass.

Nicole Grajewski, an assistant professor at Sciences Po's Center for International Research, said a US blockade was "not a minor coercive signal" but could rather be considered an effective resumption of the war.

The US military said Saturday that two US Navy warships had transited the strait to begin clearing it of mines, a claim Tehran denied.

Iran's Fars news agency reported Sunday that two Pakistan-flagged oil tankers bound for the strait had turned back.

But the strait was far from the only friction point jettisoning global efforts led by Pakistan to end the war, which began on when Israel and the US launched strikes on Iran, which retaliated by attacking Gulf and Israeli cities.

The US delegation in Islamabad -- led by Vance, special envoy Steve Witkoff and Trump's son-in-law Jared Kushner -- was frustrated by Iran's refusal to give up what it called its right to a nuclear programme.

"I have always said, right from the beginning, and many years ago, IRAN WILL NEVER HAVE A NUCLEAR WEAPON!" Trump later posted.

Vance told reporters in Islamabad that Washington had made Tehran its "final and best offer," adding: "We'll see if the Iranians accept it."

- Violence in Lebanon -

Even before the historic talks, concern had been high over whether the ceasefire could collapse due to continued Israeli strikes it says are targeting Iran-backed Hezbollah in Lebanon, where Iran and Pakistan insist the truce also applies.

Lebanese Prime Minister Nawaf Salam said Sunday he was working to stop the war and ensure Israeli troops withdrew, even as Israeli premier Benjamin Netanyahu told troops in south Lebanon that the fight there was far from over.

Lebanese and Israeli officials are due to hold talks in Washington on Tuesday.

Hezbollah said overnight it had launched rocket towards towns in northern Israel, continuing attacks that it began in early March to avenge the death of Iran's supreme leader in the opening salvo of Israeli-US strikes that began the regional war.

Israeli strikes on Beirut and other parts of Lebanon last week after the temporary ceasefire announcement had killed hundreds, according to Lebanon's health authorities.
