Ukraine wants other countries to heed its warning that Russia may be planning to attack an occupied nuclear power plant to cause a radiation disaster, President Volodymyr Zelenskyy said.

Members of his government briefed international representatives on the possible threat to the Zaporizhzhia Nuclear Power Plant. Zelenskyy said he expected other nations to “give appropriate signals and exert pressure” on Moscow.

“Our principle is simple: The world must know what the occupier is preparing. Everyone who knows must act,” Zelenskyy said late Thursday. “The world has enough power to prevent any radiation incidents, let alone a radiation catastrophe.”

The potential for a life-threatening release of radiation has been a concern since Russian troops invaded Ukraine last year and seized the plant, which is Europe’s largest nuclear power station. The head of the UN's atomic energy agency spent months unsuccessfully trying to negotiate for a safety perimeter to protect the facility as nearby areas came under repeated shelling.

The International Atomic Energy Agency noted Thursday that “the military situation has become increasingly tense” while a Ukrainian counteroffensive that got underway this month unfolds in Zaporizhzhia province, where the namesake plant is located, and in an adjacent part of Donetsk province.

Although the last of the plant's six reactors was shut down last fall to reduce the risk of a meltdown, experts have warned that one could still happen if the cooling system that keeps the reactor core and spent nuclear fuel from overheating loses power.

During months of fighting, Russia and Ukraine have traded blame over which side was increasing the possibility of that happening. On Friday, IAEA Director General Rafael Grossi met with the head of Russian state nuclear corporation Rosatom in the Kaliningrad exclave of Russia to discuss the conditions at the plant.

Rosatom director Alexey Likachev and other officials “emphasized that they now expect specific steps” from the UN agency to prevent Ukrainian attacks on the plant and its adjacent territory, said a statement from the Russian corporation, whose divisions build and operate nuclear power plants.

The governor of Zaporizhzhia, Yuriy Malashko, reported Friday that Russian shelling in the southern province killed two people in the past day. An attack that hit a transportation company in Kherson, the capital of Kherson province, killed three others on Friday, governor Oleksandr Prokudin said.

Russia also fired 13 cruise missiles overnight at a military airfield in the western Khmelnytskyi province but Ukrainian air defenses intercepted them all, according to the air force. The attack came after Russian-appointed officials said that Ukrainian-fired missiles damaged a bridge that serves as key supply link to occupied areas of southern Ukraine.

Russia's air-launched Kh-101 and Kh-555 missiles were sent from the Caspian Sea, the air force said. It did not identify the targeted airfield, but Ukraine has an air base near the Khmelnytskyi region's town of Starokostiantyniv.

The base houses fighter jets and bombers, and five years ago it hosted a training exercise with air force personnel from the United States, Ukraine and seven European countries. It has come under Russian attack previously, including within the last month.

Ukrainian Deputy Defense Minister Hanna Maliar said on Friday that Russia has beefed up its defense forces in southern Ukraine in response to the early counteroffensive but also intensified its efforts to take more ground in the east. Asked if the Ukrainian military's initial attacks set the stage for a larger assault, Maliar confirmed that was the plan.

“We are yet to see the main events, and the main blow," she said on Ukrainian television. “And indeed, a part of reserves will be used later.”

Ukrainian forces so far have made only incremental gains in Zaporizhzhia province, one of four regions of the country that Russian President Vladimir Putin illegally annexed last year. Putin has pledged to defend the regions as Russian territory.

Zelenskyy has said that Ukraine is fighting to force Russian troops out of those regions and Crimea, which Moscow is using as a staging and supply route in the 16-month-old war. If the counteroffensive now in its early stages breaks the Russian defenses in the south, Ukrainian forces could attempt to reach a pair of occupied port cities on the Sea of Azoz and break Russia’s land bridge to Crimea.

The Ukrainian leader's nighttime remarks Thursday on a possible attack on the nuclear power plant carried a tone of frustration with “countries that are pretending to be neutral even now” in the war. He accused “anyone who turns a blind eye to Russia’s occupation of such a facility” of enabling Moscow to commit an act of evil and terror.

“Obviously, radiation does not ask who is neutral and can reach anyone in the world. Accordingly, anyone in the world can help now, and it is quite clear what to do,” Zelenskyy said.

On Friday, Russia claimed it was the target of “an information and propaganda campaign to discredit the country in the international arena.” Russia’s Federal Security Service, the FSB, said five people were arrested for trying to smuggle a kilogram of the radioactive isotope Cesium-137 out of the country under the direction of a Ukrainian citizen.

The FSB said the material was to be used for “organizing staged scenes of the use of weapons of mass destruction.” Cesium-137 is often mentioned as of potential use in making a ”dirty bomb" that could contaminate a wide area.

NATO intercepted Russian strategic bombers and fighter jets that flew over the Baltic Sea on Monday, a muscular display of air power on the alliance’s eastern flank away from the spotlight on the Middle East.

French Rafale fighters were deployed from a Lithuanian air base where they are stationed as part of a decades-long NATO air-policing effort. The fighters armed with air-to-air missiles joined jets from Sweden, Finland, Poland, Denmark and Romania. They all took to the skies to inspect and keep watch on the Russian flight, the French detachment said.

The Russian mission included two supersonic Tu-22M3s, as well as about 10 fighters — both SU-30s and SU-35s — that took turns escorting the larger strategic bombers, according to the statement.

The Russian Defense Ministry said the long-range bombers' flight was scheduled and occurred in airspace over the neutral waters of the Baltic Sea. The flight took more than four hours, the ministry said Monday on Telegram.

“At certain stages of the route, the long-range bombers were accompanied by fighters of foreign states,” the ministry said. “Crews of long-range aviation regularly conduct flights over the neutral waters of the Arctic, the North Atlantic, the Pacific Ocean, as well as the Baltic and Black Seas. All flights of Russian Aerospace Forces aircraft are carried out in strict compliance with international rules for the use of airspace.”

The ministry did not immediately respond to a request for comment on Tuesday. It often reports flights by its strategic bombers over the Baltic Sea, including in January — when NATO jets also flew up to meet them — and at least four times last year.

NATO’s Allied Air Command also did not immediately respond to a request for comment on Tuesday.

The military alliance routinely scrambles fighter aircraft to intercept Russian warplanes that approach or fly near NATO airspace. NATO says the Russian planes it intercepts often fail to use their transponders and don't communicate with air traffic controllers or file a flight plan. NATO jets are sent up to identify them.

Many of the Russian flights that NATO monitors with its Baltic air policing mission, in place since Lithuania, Latvia and Estonia joined the alliance in 2004, are to and from the Russian enclave of Kaliningrad. Even before the war in Ukraine, NATO was intercepting Russian planes around 300 times each year, mostly over waters around northern Europe.

A journalist from The Associated Press witnessed the French detachment's response on Monday from the sprawling Šiauliai Air Base in Lithuania. NATO uses the base for fighter patrols that police the skies on the alliance’s eastern flank.

Two French Rafale fighter jets’ two-man crews — a pilot and a navigator — were seen racing in two vans to the planes’ hangars from the headquarters building the French detachment uses during its four-month deployment on the air base.

The crews were already suited up because they’d been on standby, so they would be ready to take to the air within minutes if scrambled.

The two crews quickly took their places in their planes’ cockpits. They were then put on hold, with the planes’ jet engines ignited, until they got the order to take off. Then they taxied out of their hangars and roared off into the clear skies.

Monday's flight was the latest in Russia's maneuvers over the Baltic Sea.

Lithuania's defense ministry said NATO jets were scrambled four times from April 13-19 to intercept Russian aircraft that violated flight rules that included turning off flight transponders and flying without a flight plan.

Iranian authorities have arrested more than 3,600 people on charges related to the US-Israeli war ranging from sharing videos with media outlets based overseas to possessing Starlink internet terminals, an NGO said on Tuesday.

Norway-based Iran Human Rights (IHR) said the figure, based on state media reports and its own research, represented a minimum given the current internet restrictions in the country, and that the actual number of arrests was "likely much higher".

It said at least 3,646 people had been arrested since the war broke out on February 28, with at least 767 of the cases reported after the start of a ceasefire on April 8.

"The charges levelled against the detainees predominantly include espionage, communicating with foreign intelligence services, transmitting images or coordinates of sensitive locations to foreign-based media, and attempting to establish operational cells or conduct armed activities," it said.

People have also been arrested for using and distributing Starlink satellite-based internet terminals to circumvent internet blackouts, and for alleged cooperation with pro-monarchist groups.

IHR said more than 100 civil society activists were among those arrested, including prize-winning rights lawyer Nasrin Sotoudeh, who was detained on April 2.

Sotoudeh's daughter Mehraveh Khandan wrote on Instagram on Saturday that her mother had telephoned for the first time since her arrest, saying she was being held by the intelligence ministry but was not allowed to disclose where.

Her fellow rights activist and 2023 Nobel Peace Prize winner Narges Mohammadi remains in prison after her arrest in December, which took place before the war and mass protests in January.

Mohammadi on Tuesday turned 54 behind the bars of her prison in the northern city of Zanjan, her foundation said, after warning last week her health was "critical" following a heart attack in March.


US Forces Board a Sanctioned Oil Tanker in the Indian Ocean, the Pentagon Says

US Forces Board a Sanctioned Oil Tanker in the Indian Ocean, the Pentagon Says

US forces have boarded an oil tanker previously sanctioned for smuggling Iranian crude oil in Asia, the Pentagon said Tuesday, as it puts into place a global warning to track down vessels tied to Tehran.

US forces “conducted a right-of-visit maritime interdiction” and boarded the M/T Tifani “without incident,” the Pentagon said on social media.

The Tifani was captured in the Bay of Bengal — between India and Southeast Asia — and was carrying Iranian oil, according to a US defense official who spoke on condition of anonymity to discuss an ongoing military operation. The US military will decide in the next four days what to do with the vessel, such as tow it back to the US or turn it over to another country, the official said.

It's the latest move in the US war on Iran to stop any ship tied to Tehran or those suspected of carrying supplies that could help its government, from weapons and oil to metals and electronics. The announcement comes ahead of the expiration of an already tenuous ceasefire between the US and Iran, and as Pakistan attempts to broker talks between Washington and Tehran.

It is the second vessel linked to Iran that has been interdicted by the US military. The US Navy attacked and seized an Iranian-flagged cargo ship Sunday that it said had tried to evade its blockade of Iranian ports, with President Donald Trump saying an American destroyer blew a hole in the ship’s engine room.

Targeting Iran-linked ships in international waters The Pentagon on social media described the Tifani as “stateless” despite it being a Botswana-flagged vessel.

“As we have made clear, we will pursue global maritime enforcement efforts to disrupt illicit networks and interdict sanctioned vessels providing material support to Iran — anywhere they operate,” the Pentagon announcement said, echoing previous statements from Trump administration officials. “International waters are not a refuge for sanctioned vessels.”

Gen. Dan Caine, chairman of the Joint Chiefs of Staff, said last week that the enforcement actions would extend beyond Iranian waters and the area under control of US Central Command.

US forces in other areas of responsibility, he told reporters at the Pentagon, “will actively pursue any Iranian-flagged vessel or any vessel attempting to provide material support to Iran.” He specifically pointed to operations in the Pacific and said the US would target vessels that left before the blockade began outside the Strait of Hormuz, a crucial waterway for energy and other shipments.

The military also detailed an expansive list of goods that it considers contraband, declaring that it will board, search and seize them from merchant vessels “regardless of location.” A notice published Thursday says any “goods that are destined for an enemy and that may be susceptible to use in armed conflict” are “subject to capture at any place beyond neutral territory.”

Blockades can be lawful in wartime, expert says

The US military’s actions against Iranian-linked vessels, namely the attack over the weekend on the cargo ship named the Touska, have raised questions about the two-week ceasefire.

The US and Iran are operating in “an awkward space where the law doesn’t give you a clean yes-or-no answer” on whether the ceasefire was violated, said Jason Chuah, a law professor at the City University of London and the Maritime Institute of Malaysia.

“The United States seems to take the line that the conflict never fully switched off — that is there is still a state of armed conflict,” Chuah said. “By saying that, it can keep doing things like enforcing a blockade and even using limited force at sea.”

But Iran is treating the ceasefire as a pause on all hostile acts, Chuah said. Iran’s joint military command has called the armed boarding an act of piracy and a violation of the ceasefire.

The US earlier had instituted a blockade against sanctioned oil tankers linked to Venezuela but had never fired on those vessels.

Blockades and even limited attacks on vessels can be lawful in wartime, with merchant vessels becoming legitimate targets if they contribute to military actions, carry contraband or are incorporated into enemy logistics, Chuah said.

It's harder to prove that a ship such as the Touska is realistically contributing to military action against the US, Chuah said.

“The whole dispute really turns on a deceptively simple question: Did the ceasefire actually suspend the right to use force?” Chuah said. “If it did, then firing on vessels or seizing them is very hard to square with the United Nations Charter.”

Mark Cancian, a retired Marine colonel and a senior defense adviser with the Center for Strategic and International Studies, said a violation is up for interpretation because there were no defined terms.

“Trump announced it. The Iranians agreed. But there’s no formal agreement,” Cancian said. “So whether it broke the ceasefire or not depends on your perspective. ... Nothing was written down.”

Michael O’Hanlon, a defense and foreign policy analyst at the Brookings Institution, said the US did not violate the ceasefire because it was limited to bombing Iran, not the blockade.

“We agreed to stop dropping bombs on them, and that’s the basic thing they wanted,” O’Hanlon said, adding that the US still had to enforce the blockade “if you’re going to make it mean anything.”
