Brent crude rises amid a continuing deadlock as Trump describes Iran’s response as ‘totally unacceptable’.

Diplomatic efforts to forge a peace deal between the United States and Iran appear to have hit a wall, with each side accusing the other of making unreasonable demands, even as continuing tensions in the Strait of Hormuz are sending oil prices to new highs.

The US-Israel war on Iran entered its 73rd day on Monday. Late on Sunday, US President Donald Trump flatly rejected Iran’s latest proposal to end the war without giving any reason. Days after the US floated an offer in the hopes of reopening negotiations, Iran on Sunday released a response focused on ending the war on all fronts, especially in Lebanon.

Oil prices climbed after Trump’s latest comments, with the international benchmark Brent crude up 2.69 percent to $104.01 a barrel by 23:36 GMT on Sunday.

Tehran’s proposal included ending the naval blockade and lifting US and international sanctions, while preserving Iran’s control over its nuclear programme and foreign policy — the issues Washington cited when launching the war.

Trump called Iran’s response to Washington’s offer “totally unacceptable”, while Iranian state media said the US plan amounted to “Iran’s surrender to Trump’s greed”.

On Sunday, the United Arab Emirates said it intercepted two drones coming from Iran, while Qatar condemned a drone attack in its waters on a cargo ship coming from Abu Dhabi. Kuwait said its air defences had dealt with hostile drones that entered its airspace.

Here is what we know about what’s been happening in the past 24 hours:

In Iran

• Iran executed a man, Erfan Shakourzadeh, 29, convicted of spying for US and Israeli intelligence services, the judiciary’s Mizan news outlet reported on Monday. It said Shakourzadeh worked at a scientific organisation involved in satellite activities and had shared classified scientific information with foreign intelligence services. He was arrested last year.

War diplomacy

• EU foreign ministers meet in Brussels: Foreign ministers of European Union nations are meeting in the Belgian capital to discuss the war on Iran as well as the Ukraine war.
• Trump-Xi meeting: Trump is set to arrive in Beijing on Wednesday evening to discuss the war on Iran and other issues with his Chinese counterpart, Xi Jinping.

In the US

• Surveys show that the war is unpopular with US voters, who are facing sharply higher petrol prices less than six months before midterm elections that will determine whether Trump’s Republican Party retains control of Congress.

In Lebanon

• Israel is carrying out air raids on the towns of Kfar Tebnit and Choukine, according to Al Jazeera Arabic, despite a US-brokered ceasefire announced on April 16.
• Two Lebanese medics and a civilian were killed in an Israeli attack on emergency response centres in Bint Jbeil.
• The Israeli military has announced the death of Alexander Glovanyov, 47, an army driver. He was killed in combat near the border with Lebanon.

Global economy

• Oil prices up: Oil prices rose by more than $4 a barrel on Monday following news of the continued stalemate that leaves the narrow Strait of Hormuz largely closed. Before the war began on February 28, the waterway carried one-fifth of the world’s oil and liquefied natural gas flows, and has emerged as one of the central pressure points in the war.
• Tankers transit the strait: While traffic through the Strait of Hormuz is at a trickle compared with pre-war times, shipping data from Kpler and LSEG showed three tankers laden with crude exited the waterway last week, with their trackers switched off to avoid Iranian attack.
• Dollar gains: The US dollar advanced for a second day against its major peers in Asian trade on Monday, supported by strong jobs data and safe-haven demand driven by a shaky ceasefire.
• Gold falls: Gold prices fell on Monday, as a lack of progress in US-Iran peace negotiations pushed oil prices higher, fuelling concerns that elevated inflation could keep interest rates higher for longer.

Hundreds protested in Mexico City on Mother’s Day to demand justice and accountability for missing loved ones. 130,000 people are registered as missing in Mexico, as of early 2026, which has been driven by organised crime and escalating violence.

Imagine the following scenario: you are scheduled to board a sailing boat as part of a large fleet carrying humanitarian aid. Some boats in the fleet had already departed ahead of you, yet days before you are scheduled to join them, the boats are violently intercepted in international waters by a foreign power acting 600 nautical miles (1,100km) from its own coast in flagrant violation of international maritime laws.

At least 30 of your fellow sea travellers were injured, and at least four have since come forward to report incidents of sexual assault. Another two, Saif Abu Keshek and Thiago Ávila, were forcibly taken to Israel, where they faced terrorism charges and were beaten and tortured while in detention. Both undertook hunger strikes in protest until their release was announced.

Hand on heart, knowing all this, would you continue sailing? More so, would you expect the overwhelming majority of your fellow travellers to do so as well?

For the great majority of the remaining participants of the Global Sumud Flotilla (GSF) – those who have not been kidnapped at sea by the Israeli navy – the answers to these questions are clear: We are sailing on.

In defiance of Israel’s genocide, and in solidarity with the Palestinian people, our fleet is moving forward. Despite experiencing or being informed of the violent interception, we are en route to the Turkish port of Marmaris, where we will regroup. I am sailing on board one of the boats as I write this.

In their long history, Gaza flotillas have often been decried as performative, except, of course, they have yielded some very concrete results: back in October, despite being violently intercepted once again, the GSF mission contributed to the mounting pressure on Israel to accept a ceasefire, which was announced days after the violent interception.

The word “performative” should instead be applied to this “ceasefire”, during which the Israeli army has continued to massacre Palestinian men, women and children and deny them humanitarian aid in adequate quantities.

Each of our missions has helped further delegitimise the Israeli state’s genocidal and warmongering tactics. And this is true for this mission as well. Already, more than 600 nautical miles from Gaza’s shores and even before it had the opportunity to fully assemble, the flotilla managed to stir international debate when 22 of its vessels were targeted.

An array of geopolitical questions has arisen, and longstanding maritime sovereignty conventions have been challenged, evincing the violation of international law. Should the Greek coastguard not have responded to the distress signals issued within its search and rescue zone? Should they not have barred the Israeli naval prison-ship from leaving the Greek port of Ierapetra, Crete, given that they were already in possession of reports of the torture and beating of the international activists inside?

As our fleet now sails eastwards, it enters a contested maritime space: the decades-long Greek-Turkish dispute over Aegean jurisdiction, where overlapping claims to airspace, territorial waters and search-and-rescue zones have remained unresolved since the 1970s. Here, the question of who is responsible when a foreign navy operates in your waters becomes harder, not easier, to answer.

Despite all this, we sail on. What we still have with us is the unwavering desire and resolve to eventually make it to Gaza. What we are faced with is an Israeli state determined to create new facts at sea, just as it has spent decades creating new facts on the ground.

Illegal Israeli settlements in the occupied West Bank have been designed to render a future Palestinian state impossible. These interceptions, increasingly ever further from Palestinian waters, are doing the same to the freedom of the seas.

Far from performative, the GSF mission has become a litmus test of Western complicity in the genocide and Israeli extraterritorial claims.

Terrifying as it might be, none of us on the boats is a fearless hero, nor did we ever claim to be; our mission has become all the more important because of what just happened in those waters. From complicit states to citizens and activists facing Israel’s wrath, it forces us all to re-evaluate. The GSF invites everyone to choose a side.
