A top UAE official denounced Iran's claim of control over Emirati waters in the blockaded Strait of Hormuz as a "pipe dream" Thursday, following an announcement by an Iranian body overseeing the strait.

"The regime is trying to establish a new reality born from a clear military defeat, but attempts to control the Strait of Hormuz or infringe on the UAE's maritime sovereignty are nothing but pipe dreams," said the United Arab Emirates' presidential advisor Anwar Gargash in a post on X.

Israel has released hundreds of activists who attempted to breach Israel's naval blockade of Gaza and are in the process of deporting them, according to a legal organization working with the flotilla.

The Israel-based legal advocacy group, the Legal Center for Arab Minority Rights in Israel, or Adalah, said Thursday that most of the international activists are in transit to a civilian airport near the southern Israeli city of Eilat for deportation.

The U.S. military said Wednesday that it boarded an Iranian-flagged oil tanker in the Gulf of Oman that was suspected of trying to violate the American blockade, the latest action by the Trump administration to try to push Tehran to reopen the Strait of Hormuz.

But President Donald Trump is facing his own pressure at home for shipping to resume through the vital corridor off Iran's coast. Fellow Republicans in Congress are battling political headwinds ahead of November's midterm elections as gasoline prices skyrocket and global energy markets churn.

As negotiations with the United States hang in the balance, a hard-line Iranian general linked to notorious attacks at home and abroad over the past decades is believed to have seized a place near the center of power.

Brig. Gen. Ahmad Vahidi, who heads Iran's paramilitary Revolutionary Guard, has become a major player in formulating Iran's tough stance in negotiating a possible end to the war with the United States, experts say. He is believed to be part of a small clique in direct contact with Iran's Supreme Leader Ayatollah Mojtaba Khameini, who remains in hiding after being reportedly wounded in the Feb. 28 Israeli strikes that killed his father, Ayatollah Ali Khamenei.

Israeli Prime Minister Benjamin Netanyahu has remained in power for most of the past 17 years due in part to a tight alliance with ultra-Orthodox religious parties.

But that alliance is tearing apart his governing coalition and proving to be another major liability for the long-serving Israeli leader as the country heads to elections later this year. The Oct. 7, 2023, attack — and the inconclusive wars that have followed — are also weighing on him.

U.S. President Donald Trump and Israeli Prime Minister Benjamin Netanyahu discussed a new effort to reach a deal with Iran in a difficult call on Tuesday, three sources told U.S. news portal Axios, with one source saying Netanyahu's "hair was on fire" after the call.

A final agreement between the U.S. and Iran may be announced within hours, unnamed sources told Al-Arabiya television on Wednesday.

Italian Prime Minister Giorgia Meloni slammed as "unacceptable" the treatment of Gaza flotilla activists detained by Israel, after an Israeli minister posted a video of them bound and forced to kneel.

"It is intolerable that these protesters, among whom there are many Italian citizens, are subjected to this treatment, which violates human dignity," Meloni said in a statement, referring to the video posted by far-right national Security Minister Itamar Ben Gvir.

Iranian Revolutionary Guard members now regularly show the public in Tehran how to handle Kalashnikov-style assault rifles. Parades through the capital feature military vehicles mounted with belt-fed Soviet-era machine guns. And at one mass wedding, a ballistic missile, like the one that rained down cluster munitions on Israel, adorned the stage.

Weapons are now regularly brandished in Tehran, an increasing show of defiance as U.S. President Donald Trump threatens he could restart the war with Iran should negotiations break down and the Islamic Republic refuses to release its grip on the Strait of Hormuz.

The UAE demanded on Wednesday that Iraq "immediately" prevent further attacks from its territory, following an accusation by the Emirates that a drone targeting a nuclear plant was launched from there.

The foreign ministry in a statement called on "Iraq to prevent all hostile acts originating from its territory urgently and without conditions", saying there was a "need to address those threats promptly, immediately, and responsibly".
