Russia-Ukraine live updates: All reactors at power plant shut down for first time in history

(NEW YORK) — Russian President Vladimir Putin’s “special military operation” into neighboring Ukraine began on Feb. 24, with Russian forces invading from Belarus, to the north, and Russia, to the east. Ukrainian troops have offered “stiff resistance,” according to U.S. officials.

The Russian military has since launched a full-scale ground offensive in eastern Ukraine’s disputed Donbas region, capturing the strategic port city of Mariupol and securing a coastal corridor to the Moscow-annexed Crimean Peninsula.

Zaporizhzhia ‘one step away’ from emergency radiation: Ukraine nuclear agency head

The head of Ukraine’s nuclear agency, Petro Kotin, called Thursday’s disconnection of power lines at Zaporizhzhia, Europe’s largest nuclear power plant, a “very serious deterioration… due to Russian shelling on the side of Nikopol on the side of the Dnipro river.”

The diesel generator operators were able to kick in during the disconnection, Kotin told ABC News on Friday.

Asked what’s the likelihood this would happen again, Kotin said, “This is one step from the emergency radiation, actually. Diesel is just the last defense, if you actually lose the diesel stuff, you already have radiation, and it’s out of the territory of the plant.”

He said there’d be 10 days of idle time before a meltdown if the diesel generators are working. If all diesel generators are down, it could be 1.5 hours.

For Russia, the Zaporizhzhia plant is a strategic stronghold as it seeks to control the ground pathway from occupied Donetsk to Crimea and onto Odesa.

Zaporizhzhia supplies Ukraine with around 20% of its energy.

Kotin reiterated that Russia intends to switch power to Russian-controlled areas.

All reactors at power plant shut down for 1st time in history

All of the reactors at Zaporizhzhia nuclear power plant, where shelling has been ongoing, have been shut down for the first time in the plant’s history, Ukraine’s state nuclear regulator Energoatom reported.

Zaporizhzhia — the largest nuclear power plant in Europe — has six reactors, two of which are active, according to Ukraine’s state nuclear regulator, Energoatom. At 12:12 p.m. local time, the last operating line providing power to the plant was disconnected due to hostilities in the area, and as a result all six reactors were disconnected from the grid for 17 minutes, Energoatom said.

At 12:29 p.m. local time the overhead line was restored and reactors Nos. 5 and 6 start operating again.

At 2:14 p.m. local time, the overhead line was disconnected again, shutting down reactor No. 6 and leaving only reactor No. 5 operating. Work is underway to reconnect No. 6 to the grid.

The International Atomic Energy Agency said the temporary shut down further shows “the urgent need for an IAEA expert mission to travel to the facility.”

If external power is lost there’s not active circulation of the water that cools the reactor and that could lead to a reactor meltdown. However, the plant “remained connected to a 330 kV line from the nearby thermal power facility that can provide back-up electricity if needed,” the IAEA said in a statement. “As a result of the cuts in the 750 kV power line, the ZNPP’s two operating reactor units were disconnected from the electricity grid and their emergency protection systems were triggered, while all safety systems remained operational.”

“There was no information immediately available on the direct cause of the power cuts,” the IAEA said. “The six-reactor ZNPP normally has four external power lines, but three of them were lost earlier during the conflict. The IAEA remains in close contact with Ukraine and will provide updated information as soon as it becomes available.”

Ukrainian President Volodymyr Zelenskyy warned Thursday, “The world must understand what a threat this is: If the diesel generators hadn’t turned on, if the automation and our staff of the plant had not reacted after the blackout, then we would already be forced to overcome the consequences of the radiation accident. Russia has put Ukraine and all Europeans in a situation one step away from a radiation disaster.”

He called on the IAEA and other international organizations to act faster, “because every minute the Russian troops stay at the nuclear power plant is a risk of a global radiation disaster.”

Biden, Zelenskyy discuss weapons assistance, nuclear plant during phone call

President Joe Biden and Ukrainian President Volodymyr Zelenskyy spoke about weapons assistance and concerns over the Zaporizhzhia nuclear plant in their phone call on Thursday, White House press secretary Karine Jean-Pierre said.

Regarding Zaporizhzhia, “We have said Russia should agree to demilitarize the zone around the plant and agree to allow an International Atomic Energy Agency visit as soon as possible,” Jean-Pierre said. “This is something that did come up in a conversation.”

Zelenskyy tweeted a photo of his phone call with Biden, and said he thanked him “for the unwavering U.S. support for Ukrainian people — security and financial.”

Zelenskyy said he and Biden “discussed Ukraine’s further steps on our path to the victory over the aggressor and importance of holding Russia accountable for war crimes.”

Biden also tweeted a photo of the call, and said he congratulated Ukraine on its Independence Day, which was on Wednesday.

“I know it is a bittersweet anniversary, but I made it clear that the United States would continue to support Ukraine and its people as they fight to defend their sovereignty,” Biden wrote.

Russia may hold sham referenda in occupied Ukrainian territory: White House

The White House said the U.S. believes Russia could hold “sham referenda” in occupied Ukrainian territory within days or weeks.

White House spokesman John Kirby said last month that Russia was “installing illegitimate proxy officials in the areas of Ukraine that are under its control” who would then arrange “sham referenda” as a precursor to annexation.

Kirby told reporters Wednesday that the U.S. government believes “these referenda could begin in a matter of days or weeks.”

“We have information that Russia continues to prepare to hold these sham referenda in Kherson, Zaporizhzhia, the so-called Donetsk and Luhansk People’s Republics,” Kirby said. “We’ve also learned that Russian leadership has instructed officials to begin preparing to hold these sham referenda, particularly in Kharkiv, as well.”

“We expect Russia to try to manipulate the results of these referenda to falsely claim that the Ukrainian people want to join Russia,” he continued. “It will be critical to call out and counter this disinformation in real time.”

“Any claim that the Ukrainian people somehow want to join Russia is simply not true,” Kirby said, citing polling data. It’s clear, he added, that Ukrainians “value and treasure their independence.”

President Joe Biden and Ukrainian President Volodymyr Zelenskyy will speak on the phone on Thursday, Kirby said.

Biden announces new aid package, congratulates Ukraine on Independence Day

President Joe Biden in a statement Wednesday said he was “proud to announce our biggest tranche of security assistance to date” to Ukraine: “approximately $2.98 billion of weapons and equipment.”

“This will allow Ukraine to acquire air defense systems, artillery systems and munitions, counter-unmanned aerial systems, and radars to ensure it can continue to defend itself over the long term,” Biden said.

Biden confirmed the money would come through the Ukraine Security Assistance Initiative. The USAI money can be spent on contracts with the defense industry to produce new equipment for Ukraine.

Biden in his statement also marked Ukrainian Independence Day, saying, “Ukrainians have inspired the world with their extraordinary courage and dedication to freedom.”

“Today is not only a celebration of the past but a resounding affirmation that Ukraine proudly remains — and will remain — a sovereign and independent nation,” he said.

He continued, “I know this Independence Day is bittersweet for many Ukrainians as thousands have been killed or wounded, millions have been displaced from their homes, and so many others have fallen victim to Russian atrocities and attacks.”

“Today and every day, we stand with the Ukrainian people to proclaim that the darkness that drives autocracy is no match for the flame of liberty that lights the souls of free people everywhere,” Biden said.

US to announce its largest single aid package for Ukraine

The U.S. will announce its largest single aid package for Ukraine on Wednesday, according to two U.S. officials. The package is expected to be valued at roughly $3 billion — though one official told ABC News some changes could be made overnight, and $3 billion is on the higher end of the estimates.

A senior U.S. official told ABC News the package will come from Ukraine Security Assistance Initiative funds. Unlike presidential drawdown packages, which pull from existing U.S. equipment stocks, the USAI money can be spent on contracts with the defense industry to produce new equipment for Ukraine.

The U.S. has committed about $10.6 billion in military aid to Ukraine since the beginning of the Biden administration.

Americans urged to leave Ukraine over Russian strikes on civilians

The United States is once again urging its citizens to leave Ukraine amid concerns Russia is ramping up attacks on civilians in the war-torn country.

In a security alert posted Tuesday on its website, the U.S. Embassy in Kyiv urged Americans “to depart Ukraine now using privately available ground transportation options if it is safe to do so.”

“The Department of State has information that Russia is stepping up efforts to launch strikes against Ukraine’s civilian infrastructure and government facilities in the coming days,” the embassy said in the alert. “Russian strikes in Ukraine pose a continued threat to civilians and civilian infrastructure.”

Sources within the State Department said the heightened risk of a Russian strike on highly populated centers is most directly tied to Ukraine’s Independence Day on Wednesday.

“The risks are really high,” Ukrainian President Volodymyr Zelenskyy told ABC News. “We are receiving information that there may be a provocation by the Russian Federation, by the occupiers. Therefore, we do not want large gatherings on such days. The days are beautiful, but … our neighbors are not.”

FSB accuses Ukrainian special services of assassinating Darya Dugina

Russia’s FSB is accusing Ukrainian special services of assassinating Darya Dugina, the daughter of Putin ally Alexander Dugina, who was killed by an explosive this weekend.

The FSB said a Ukrainian national arrived in Russia on July 23 with her 12-year-old daughter and rented an apartment in the same Moscow building where Dugina lived, Russia’s state-run RIA Novosti reported. The woman allegedly trailed Dugina for nearly a month and then immediately left for Estonia with her daughter just after this weekend’s bombing.

Russian President Vladimir Putin said in a statement that Darya Dugina was “a bright, talented person with a real Russian heart – kind, loving, sympathetic and open.”

Mykhailo Podolyak, an adviser to Ukrainian President Volodymyr Zelenskyy, said Ukraine is working under the assumption that Russian secret services are behind the killing, saying “Ru-propaganda lives in a fictional world.”

Explosive under Putin ally’s car was remotely triggered, investigators say

An explosive device planted on the underside of Putin ally Alexander Dugin’s vehicle was remotely triggered, Russian investigators said.

Dugin’s daughter, Daria Dugina, was killed in a blast near Moscow on Saturday.

“A presumed explosive device planted on a Toyota Land Cruiser went off when the car was moving at full speed past Bolshiye Vyazemy in the Odintsovo urban district at about 9 p.m. on August 20, and the car caught fire,” the Russian Investigative Committee said in a statement posted to Telegram. “The woman driving the car died instantly. The victim was identified as journalist, political analyst Daria Dugina.”

Alexander and Daria attended a traditional patriotic festival on Saturday afternoon, according to the Odinstovo administration. They’d planned to leave together in the same vehicle, but Daria instead drove alone.

The Russian Investigative Committee’s press service told Interfax that Daria was assassinated.

Detectives established that the bomb was planted on the underside of the driver’s side of the vehicle, the committee said. Russian media outlets had reported that the SUV belonged to Dugin.

“Detectives and specialists from the Main Forensic Department of the Russian Investigative Committee are continuing to examine the incident scene. In particular, a forensic technician examined the charred vehicle before it was taken to a special parking lot,” the Committee said.

Biological, genetic, physical, chemical and explosive examinations have been scheduled, the committee said.

Daughter of Putin ally killed in car bomb; Schiff hopes it wasn’t ‘from Ukraine’

U.S. officials do not know who to blame for the car bomb that killed the daughter of political theorist Alexander Dugin, a close ally of Russian President Vladimir Putin, Rep. Adam Schiff, the Democratic chair of the House Intelligence Committee, said during an interview Sunday on CNN’s “State of the Union.”

Daria Dugina, a 29-year-old TV commentator, was killed on the Mozhaisk Highway in the outskirts of Moscow on Saturday night by an explosive that had been planted in the Toyota Land Cruiser she was driving, Russia’s state-run news agency TASS reported.

Alexander Dugin, often referred to as “Putin’s brain,” had just attended “Tradition” cultural festival with his daughter, according to TASS. Russian media outlets reported that the SUV belonged to Dugin.

The Russian Investigative Committee press office told TASS Dugina’s killing was planned and contracted.

Schiff said Sunday that he had not yet been briefed on the killing and that he “couldn’t say” who is behind it, adding that he hoped it was an “internal Russian affair” rather than something “emanating from Ukraine.”

“There are so many factions and internecine warfare within Russian society, within the Russian government,” Schiff said. “Anything is possible.”

Adviser to the Ukrainian presidential office Mikhail Podolyak denied Kyiv was involved in the explosion that killed Dugina during a televised interview on Sunday.

“I emphasize that Ukraine certainly has nothing to do with this, because we are not a criminal state like the Russian Federation, and even less a terrorist state,” Podolyak said.

US to offer new $775M aid package to Ukraine

The U.S. has authorized a new $775 million military aid package for Ukraine, the Department of Defense announced on Friday.

The package will include more High Mobility Artillery Rocket System (HIMARS) ammunition and howitzers, as well as some firsts, including ScanEagle reconnaissance drones and Mine Resistant Ambush Protected (MRAP) vehicles.

The 15 ScanEagle drones are intended to help Ukraine identify targets and put the HIMARS and howitzers to better use, according to a senior U.S. defense official.

The 40 MRAP vehicles and other mine-clearing equipment will help Ukrainian troops cross dangerous terrain, according to the official.

“We know that Russia has heavily mined areas in parts of southern and eastern Ukraine. We know there’s a significant amount of unexploded ordinance,” the official said.

The new aid package follows a $1 billion package announced on Aug. 8.
