The Israeli foreign ministry said Spanish activist Saif Abu Keshek and Brazilian activist Thiago Avila were expelled after being arrested on April 29 when Israeli forces intercepted the Global Sumud Flotilla in international waters and escorted the vessel to Israel.

According to the foreign ministry, Abu Keshek was suspected of affiliation with a terrorist organization, while Avila was suspected of illegal activity. Both activists rejected the allegations, saying they had participated in a humanitarian mission aimed at delivering aid to civilians in Gaza and describing their detention outside Israeli territorial waters as unlawful.

The activists were part of a second Global Sumud Flotilla mission launched from Spain on April 12 in an attempt to breach Israel’s long-standing blockade on Gaza by sea.

Images released from court proceedings earlier this month showed both men appearing before Israeli judicial authorities following their detention.

Israel has maintained tight restrictions on Gaza since Hamas took control of the territory in 2007, citing security concerns and the need to prevent weapons smuggling. Hamas, which governs much of the enclave, is designated as a terrorist organization by Israel, the United States and several Western governments.

International scrutiny over access to humanitarian aid has intensified during the Gaza war triggered by Hamas’ Oct. 7, 2023, attack on southern Israel. The conflict has displaced large portions of Gaza’s population and sharply increased dependence on external assistance.

Humanitarian agencies and international organizations have repeatedly warned that aid deliveries into Gaza remain insufficient to meet civilian needs amid widespread destruction and deteriorating living conditions.

The flotilla interception has also drawn criticism from some United Nations experts and rights advocates, who have questioned the legality of detaining activists operating in international waters.

In a post on X, Qalibaf accused Donald Trump of attempting to turn diplomacy into a “table of surrender,” adding that Tehran was instead preparing “to reveal new cards on the battlefield.”His remarks come as a two-week ceasefire in a conflict that has killed thousands and disrupted global markets, particularly energy supplies, is set to lapse later this week.

The truce has come under strain following a U.S. move to seize an Iranian cargo vessel accused of violating a maritime blockade, prompting Tehran to warn of retaliation.

Iran has consistently rejected negotiations conducted under coercion, while Washington has maintained pressure through military and economic measures as part of its broader strategy toward Tehran.

Treasury Secretary Scott Bessent said the administration had cautioned governments and banks that continued transactions involving Iranian oil could trigger punitive measures. “If you are buying Iranian oil, that if Iranian money is sitting in your banks, we are now willing to apply secondary sanctions,” he told reporters at the White House.

The warning comes as the U.S. enforces a naval blockade on Iran that began earlier this week, with officials saying they expect the move to curb purchases by key buyers, particularly China, which has accounted for the majority of Iran’s seaborne oil exports.

Bessent said the Treasury had contacted two Chinese banks, warning that they could face sanctions if evidence shows Iranian funds moving through their systems. China’s embassy in Washington did not immediately respond to requests for comment.

Separately, the U.S. Treasury announced sanctions targeting Iran’s oil transportation network, including more than two dozen individuals, companies and vessels, as part of a broader effort to disrupt the country’s energy exports.

The measures follow the administration’s decision not to renew a 30-day sanctions waiver issued on March 20 that had allowed Iranian oil shipments already at sea to reach global markets.

The waiver, which Bessent said facilitated the delivery of about 140 million barrels, is set to expire on April 19.Washington has also allowed a similar waiver covering Russian oil shipments to lapse, reinforcing its broader sanctions enforcement strategy.

U.S. officials said letters had been sent to jurisdictions including China, Hong Kong, the United Arab Emirates and Oman, identifying financial institutions allegedly linked to Iranian transactions and warning of potential enforcement actions.

The steps are part of what the administration has described as a “maximum pressure” campaign aimed at curbing Iran’s oil revenues and limiting its ability to finance regional activities.

The announcement came a day after talks in Pakistan ended without agreement, underscoring persistent divisions over terms to end a conflict launched on Feb. 28 by the United States and Israel. The blockade is aimed at pressuring Iran to reopen the Strait of Hormuz and accept a broader settlement addressing its nuclear and missile programs, as well as its regional activities.

Trump indicated that diplomatic channels remain open, saying Iran had reached out to explore a possible resolution. “We’ve been called by the right people … and they want to work a deal,” he told reporters outside the White House.Iran signaled conditional openness to negotiations.

Judiciary chief Gholam Hossein Mohseni Ejei said discussions must proceed on the basis of “principles and logic,” while other officials warned that Tehran would respond if the situation escalates.The blockade drew sharp reactions from Iran, which threatened countermeasures targeting ports across the Arabian Gulf and Gulf of Oman, raising the risk that the two-week ceasefire declared earlier could collapse before its April 22 expiry.

At the core of the dispute remain differences over Iran’s nuclear program and control of the Strait of Hormuz, a critical global energy corridor through which roughly one-fifth of the world’s oil supply typically passes. Its closure has already disrupted markets and driven up oil prices.

U.S. Vice President JD Vance, who led the American delegation in the recent talks, said Iran had not provided assurances it would refrain from pursuing nuclear weapons capability. Tehran has long denied such intentions while defending its right to civilian nuclear development, including uranium enrichment.

Iran’s negotiating position, articulated by Parliament Speaker Mohammad Bagher Qalibaf, emphasized sovereignty over the strait, an end to hostilities, and compensation for wartime damage.

Iranian officials also dismissed the blockade as exaggerated, with parliamentary spokesperson Ebrahim Rezaei describing it as “more bluffing than reality.”Pakistan has indicated it may facilitate further dialogue, with Foreign Minister Ishaq Dar expressing willingness to host another round of talks, though no timeline has been confirmed.

Both sides have maintained firm public positions, with Trump warning that any Iranian attempt to challenge the blockade would be met with force, while Iranian foreign ministry spokesperson Esmaeil Baqaei said the measure risked further destabilizing the global economy.

IEA Executive Director Fatih Birol said that while March deliveries largely reflected cargoes loaded before the crisis escalated, the situation has shifted significantly. “During the month of April, nothing has been loaded,” he told reporters following meetings at the International Monetary Fund, adding that prolonged disruption would intensify market pressures.

Birol said the agency is tracking damage to energy infrastructure across the region, noting that more than a third of over 80 affected facilities have sustained severe damage. He described the situation as a major energy security challenge with global implications, warning that no country would be insulated from the fallout.

IMF Managing Director Kristalina Georgieva said there is an urgent need to assess the scale of economic impact stemming from infrastructure losses tied to the conflict.World Bank President Ajay Banga said the institution is preparing for multiple scenarios depending on the duration and intensity of hostilities, including expanded financial support.

The IMF has indicated it can make up to $50 billion available, while the World Bank has outlined potential financing of up to $25 billion, with the possibility of increasing total support to $60 billion over six months if conditions worsen.

The conflict, triggered by U.S.-Israeli strikes on Iran beginning February 28, has disrupted flows through the Strait of Hormuz, a critical artery for global oil shipments. Iran’s actions to impede maritime traffic, followed by a U.S. naval blockade, have heightened concerns over supply constraints and price volatility.

Although a two-week ceasefire was agreed last week to enable negotiations, talks in Islamabad failed to produce a breakthrough, raising uncertainty over whether the truce will hold.

International mediators, including Pakistan and Qatar, have urged both sides to maintain the ceasefire, while UN Secretary-General Antonio Guterres called for the restoration of freedom of navigation in the region.

The bottleneck includes 12 very large gas carriers and 50 very large crude carriers, with only six ships transiting the strait between Tuesday and Wednesday, far below the typical daily average of around 120 vessels in peacetime, data from maritime analytics firm Kpler showed.

Limited movement has been permitted through a tightly controlled corridor near Iran’s Larak Island, with access largely restricted to vessels linked to Iran or countries maintaining favorable relations with Tehran. Lloyd’s List estimates that at least 48 ships have passed through the route since last week under such arrangements.

Iran imposed the blockade following strikes by the United States and Israel on Feb. 28, effectively constraining a waterway that normally handles about one-fifth of global oil and gas shipments. Shipowners granted passage have reportedly faced fees of up to $2 million per transit, although Tehran has indicated that vessels from allied nations may be exempt.

Malaysian authorities said tankers operated by companies including Petronas, Sapura Energy and MISC were awaiting clearance, with Iran assuring Kuala Lumpur that fees would be waived due to bilateral ties. Officials cautioned that heavy congestion could delay passage regardless of exemptions.

China said at least three of its vessels had recently transited the strait following coordination with relevant parties. Ship-tracking data indicated that two container ships exited the Gulf on a subsequent attempt while sailing in close formation and at increased speed, in what analysts described as the first such movement by non-Iranian container vessels since the escalation began.

A small number of other ships have also managed to leave, including a Greek-operated tanker carrying Saudi crude to India and several Indian-flagged liquefied petroleum gas carriers transporting essential cargo.

Shipping sources said some crews have adopted risk mitigation measures such as nighttime navigation or disabling tracking systems to reduce exposure to threats including mines, missiles and drones.Despite limited transits, exports from major Gulf producers such as Saudi Arabia and Qatar remain largely suspended, with hundreds of vessels and an estimated 20,000 seafarers still awaiting clearance in and around the Gulf.

A Pakistani oil vessel reached Karachi after successfully transiting the strait, while another shipment arrived via an alternative route. Officials said further deliveries could follow in the coming weeks.The disruption has intensified diplomatic efforts to reopen the waterway.

Britain is preparing to host talks involving around 35 countries to address maritime security, while China and Pakistan have jointly called for a ceasefire and urged all sides to ensure safe passage for commercial shipping.U.S.

President Donald Trump reiterated on Wednesday that Iran must lift the blockade, warning of potential military action if it fails to comply.
