Russia invades Ukraine

The Director of Russia's space agency Roscosmos, Dmitry Rogozin, published a series of inflammatory tweets on Saturday suggesting Russia might end cooperation at the International Space Station (ISS) due to international sanctions on the country's capital, Moscow.

"I believe that restoration of normal relations between partners at the International Space Station and in other joint projects is possible only after full and unconditional removal of the illegal sanctions," Rogozin said in posts to his verified Twitter account. 

Rogozin warned that Roscosmos would prepare "concrete proposals to our country's leadership" on the possibility of ending cooperation at the ISS with the space agencies of the US, Canada, the European Union and Japan.

Some background: The head of Russia's space agency has a reputation for playing fast and loose on social media, making comments on geopolitical issues and directing criticism at the US.

NASA maintains that it has a close working relationship with Roscosmos that is unaffected by the political situation on earth and the war in Ukraine. 

Rogozin previously posted a heavily edited CGI video that appeared make the threat that Russian cosmonauts would abandon NASA astronaut Mark Vande Hei in space. Vande Hei, who launched to the ISS in April 2021, returned to earth on March 30, along with Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov.

Veteran former astronaut Scott Kelly recently told CNN he would back off his high-profile Twitter war with Rogozin, following a warning from a NASA official that such attacks are “damaging” to the ISS mission. 

Since November 2000, the ISS has functioned as an orbiting laboratory 227 nautical miles (420 kilometers) above our planet, as well as a home to continuously rotating crews of astronauts and cosmonauts. It has been the site of multiple firsts as astronauts have successfully sequenced DNA and feasted on crops grown in space.

At least four people were injured by explosions amid protests against Russian occupation in the central Ukrainian town of Enerhodar, the country's state nuclear power company Energoatom said in a series of statements Saturday. 

The city, which is close to the Zaporizhia nuclear power station seized by Russian forces in early March, has seen sporadic protests since its occupation. 

Energoatom posted video from the scene that appeared to show crowds being dispersed by automatic weapons fire and flash-bang rounds. 

The post also called the Russian military "bastards."

Energoatom said residents initially gathered for a peaceful rally in support of Ukraine. According to that account, Russian prison buses pulled up and the Russians began detaining locals

According to Energoatom, several citizens were hospitalized with injuries and severe burns due to blasts that hit a line of civilians in the vicinity of a local cultural center.

"Local doctors are doing their best in the difficult conditions of almost complete lack of drugs and materials and trying to save their lives and health," the statement said. "Some of the victims will be released today after the necessary procedures."

Evacuations efforts continue in Ukraine, with a total 6,266 people evacuated from cities on Friday, according to the country's Deputy Prime Minister Iryna Vereshchuk. Of that number, 771 people originally came from the besieged southern port city of Mariupol.

Meanwhile, Russian forces said they struck a major oil refinery in Ukraine on Saturday morning using high-precision weaponry.

Here's what you need to know:

Evacuations ongoing: Seven evacuation corridors along key routes are expected to open in Ukraine on Saturday, Vereshchuk announced in a Facebook post on Saturday. She said the list includes the route from the besieged southern city of Mariupol to the government-held city of Zaporizhzhia in southeastern Ukraine, as well as routes from Berdiansk, Rubizhne, Nizhny, Severodonetsk, Popasna and Lysychansk.

Russia attacks Ukrainian oil refinery: Russian forces targeted a major Ukrainian oil refinery in a series of strikes Saturday morning, according to a spokesman for the country's military. The refinery, in the central city of Kremenchuk, was hit by "high-precision long-range air and sea-based weapons," Russian defense ministry spokesman Igor Konashenkov said in a briefing. He said Russia's military had destroyed storage facilities holding gasoline and diesel fuels that were supplying Ukrainian troops in the country's eastern and central regions. Russia also struck military airfields in Poltava and Dnipro, cities to the east of Kremenchuk, using high-precision air-based missiles, Konashenkov said.

Moscow's warning for London: Russia would consider British long-range artillery and anti-ship systems "legitimate targets" if they United Kingdom were to deliver those weapons to the Ukrainian military, Russia's ambassador to the UK said.

“Any weapon deliveries are destabilizing," Ambassador Andrei Kelin told Russian state news agency TASS. "They exacerbate the situation and make it bloodier."

Russian officials have long complained about deliveries of advanced military weaponry to Ukraine by the US and the UK. Some of those armaments, particularly anti-tank weapons, have enabled Ukrainian troops to blunt Russian advances. 

Cold-calling Russia: In an attempt to pierce Russian President Vladimir Putin's digital iron curtain, some people are cold calling or messaging strangers in Russia to counter the Kremlin's propaganda about the war in Ukraine. They hope the truth will better inform Russian citizens and perhaps even help put an end to the conflict.

Seven evacuation corridors along key routes are expected to open in Ukraine on Saturday, according to Ukrainian Deputy Prime Minister Iryna Vereshchuk. 

Announcing the corridors in a Facebook post Saturday, Vereshchuk said the list includes the route from the besieged southern city of Mariupol to the government-held city of Zaporizhzhia in southeastern Ukraine.

Private transport will travel along the evacuation route, stopping in Mangush, Berdiansk, Tokmak, Vasylivka and Kamyanske, before reaching the final destination of Zaporizhzhia.

Vereshchuk announced in a video message on Friday evening that a convoy of 42 buses traveling from the southern city of Berdiansk -- carrying residents from the besieged city of Mariupol -- had managed to pass a key Russian checkpoint, and was en route to Zaporizhzhia. That convoy arrived in Zaporizhzhia later that night. 

Vereshchuk hailed the arrival as a success, after the Ukrainian government's efforts to try and "open the corridors from Mariupol to Zaporizhzhia" since March 5. 

A total of 6,266 people were evacuated from Ukrainian cities on Friday, including 1,431 people who moved from the southern cities of Berdiansk and Melitopol in their own vehicles to Zaporizhzhia through evacuation corridors, according to Vereshcuk. She added that of that number, 771 people originally came Mariupol.

A route for buses and private vehicles from Berdiansk to Zaporizhzia is also expected to operate on Saturday, with stops planned in Tokmak, Vasylivka and Kamyanske. 

Evacuation routes will also open from the city of Rubizhne in the separatist controlled region of Luhansk to Bakhmut in the eastern region of Donetsk, also controlled by Russian-backed separatists. 

The remaining routes will operate from Nizhny to Bakhmut, Severodonetsk to Bakhmut, Popasna to Bakhmut and Lysychansk to Bakhmut.

Russian forces targeted a major Ukrainian oil refinery in a series of strikes Saturday morning, according to a spokesman for the country's military.

The refinery, in the central Ukrainian city of Kremenchuk, was hit by "high-precision long-range air and sea-based weapons," Russian Defense Ministry spokesman Maj. Gen. Igor Konashenkov said in a briefing on Saturday. 

Konashenkov said Russia's military had destroyed storage facilities holding gasoline and diesel fuels that were supplying Ukrainian troops in the country's eastern and central regions.

Russia also struck military airfields in Poltava and Dnipro, cities to the east of Kremenchuk, using high-precision air-based missiles, Konashenkov said.

What Ukraine is saying: Dmytro Lunin, the governor of the Ukranian region of Poltava where the refinery is located, said three Russian planes carried out the strike at about 6 a.m. local time. Lunin said it is unknown whether anyone was hurt in the attack, but that emergency services were putting out a fire on Saturday morning.

Lunin also said that four Russian missiles hit other targets in Poltava at around 2 a.m. 

Ukraine’s largest oil company Ukrnafta operates an oil refinery in Kremenchuk, according to the company.

Some context: The attack on the oil refinery comes a day after the Kremlin accused Kyiv of mounting a helicopter attack on a civilian fuel depot inside Russian territory. Footage of the facility engulfed in flames has surfaced on social media.

The Ukrainian Ministry of Defense has neither confirmed nor denied the attack, and President Volodymyr Zelensky declined to discuss the assault when asked about it during an interview with Fox News.

CNN is so far unable to verify this claim and the Ukrainian Defense Ministry told CNN it has no information about the incident. 

Russia has targeted fuel storage facilities around Ukraine in recent days.

If Britain delivers long-range artillery weapons and anti-ship systems to Ukraine, they would be "legitimate targets" for Russian forces, Russian ambassador to the United Kingdom Andrei Kelin told Russian state news agency TASS in an interview published on Saturday. 

“Any weapon deliveries are destabilizing, especially the ones mentioned by (Ben) Wallace (the British Defense Secretary)," said Kelin, according to TASS. "They exacerbate the situation and make it bloodier."

“I have a feeling that London’s idea of what is happening in Ukraine militarily is formed on the basis of the bravado reports of the Ukrainian Ministry of Defense and the Ukrainian leadership," Kelin said. 

Some background: Russian officials have long complained about deliveries of advanced military weaponry to Ukraine by the US and the UK. Some of those weapons, particularly anti-tank weapons, have enabled Ukrainian troops to blunt Russian advances. 

The UK ratcheted up military support to Ukraine ahead of Russia's invasion on February 24. Following an international donor conference for Ukraine, British Defense Secretary Ben Wallace announced on Thursday that Britain and its allies will send "more lethal aid" to Kyiv.  

"There'll be more lethal aid going into Ukraine as a result of today. A number of countries have come forward either with new ideas or pledges for more money," Wallace said, noting that the United States is "being at the forefront" of the aid effort.  

Six weeks ago, Hungary's election campaign looked and sounded very different.

The stakes were already high. Viktor Orban, the longest-serving national leader in the European Union, was seeking to extend his authoritarian premiership deep into its second decade. His rival, leading a united front of opposition parties, bluntly denounced Orban's crusade against independent institutions and the rule of law.

But the political focus was resolutely domestic. When foreign policy took center stage, it was usually raised by Orban to tout his international credentials -- such as on February 1, when he boasted of his political longevity while in Moscow, a few feet from his staunch ally President Vladimir Putin.

Now, everything has changed. Putin's invasion of Ukraine later that same month has upended the race, recasting its protagonists and rewriting their pitches. It has left Orban, widely regarded as the EU's most pro-Kremlin leader, walking a political tightrope. And it has shone a spotlight on a years-long entanglement between him and the Russian President, two strongmen whose political journeys bear some notable similarities.

Viktor Orban, the EU leader who can't quit Putin, faces a united front in Hungary's election

Russian President Vladimir Putin often evokes the Soviet Union's epic defeat of Nazi Germany during World War II to justify his country's invasion of Ukraine.

Yet Putin is committing some of the same blunders that doomed Germany's 1941 invasion of the USSR -- while using "Hitler-like tricks and tactics" to justify his brutality, military historians and scholars say.

This is the savage irony behind Putin's decision to invade Ukraine that's become clear as the war enters its second month: the Russian leader, who portrays himself as a student of history, is floundering because he hasn't paid enough attention to the lessons of the "Great Patriotic War" he reveres.

"I have been trying to make sense of this for a month, because as terrible as Putin is, you could never say he was illogical," says Peter T. DeSimone, an associate professor of Russian and Eastern European history at Utica University in New York.

"All of this is illogical, and that's the scary thing," he says. "This is not normal for what he's done in the past. This is something that makes no sense on many levels, and not just in regard to World War II."

Putin is making the same mistakes that doomed Hitler when he invaded the Soviet Union

Marija Stonyte picks up her phone and anxiously dials in a number. After a couple of rings, a woman picks up.

"I'm calling to tell you a very important message. I don't know if you know a lot about what is actually happening right now in Ukraine," Stonyte says in the call last month, her voice trembling as her 1-year-old daughter babbles in the background.

There's silence on the other end of the line.

This is one of dozens of cold calls that Stonyte and her husband make every day to people in Russia from their home in Lithuania as part of a volunteer initiative aimed at penetrating Russia's so-called digital iron curtain.

Russia's ongoing onslaught in Ukraine has seen cities bombarded, civilians killed, and more than 4 million flee the country. But at home, many Russians know little about what is unfolding.

Digital iron curtain: Russia has banned state media from calling Russian President Vladimir Putin's "special military operation" an "invasion" or a "war," and those who criticize the offensive can face severe punishment.

A Moscow court banned Facebook and Instagram for carrying out "extremist activity," and a new censorship law made publishing "fake" information about the invasion punishable by up to 15 years in prison. The pressure has forced independent news outlets to pull out or shut down, leaving a void for state media to fill with propaganda and disinformation.

Desperate to break through, people around the world are trying creative ways to connect with Russians. Online activists Anonymous claim to have hacked Russian TV channels to broadcast footage from Ukraine.

Others, like Stonyte, are trying a more individual approach. They're cold calling or messaging strangers in Russia, hoping their personal pleas will disrupt the Kremlin's propaganda —  and potentially even help put an end to the deadly war.
