Just look at these horrifying images. A father is weeping in despair beside the body of his 15-year-old daughter, whom a Russian missile killed today right in the downtown of Chernihiv.
Russia is the greatest barbarian in the history of humankind🤬🤬🤬🤬🤬

[Volodymyr Zelenskyy / Володимир Зеленський @ZelenskyyUa]

A horrific Russian strike on the railway station in Dnipro. The Russians launched a drone attack on a platform where an ordinary commuter train and a scheduled passenger train were standing. Unfortunately, 13 people have been confirmed killed as of now. My condolences to their families and loved ones. Ten more people were injured. All necessary emergency services are working at the scene.

Just how many terrorist strikes has Russia carried out against our people since sanctions were lifted on certain Russian oligarchs and the Russian energy sector, rather than de-escalating? This is precisely why Ukraine has always said that just and decisive action by America and Europe is needed in response to Russian escalation – sanctions against Moscow and its war machine must not be eased for as long as this Russian war continues. It is time for new, stronger sanctions steps by the EU, the United States, and the G7. I thank everyone who is ready to help in this way.

Check out the peculiar vacuolated cell change in this banal fundic gland polyp. This change, possibly related to proton pump inhibitors, sometimes results in concern for in situ signet ring cell carcinoma, which appears different (the high magnification image).

Langerhans cell histiocytosis (LCH) can present as colorectal polyps in adults and is generally indolent - analogous to to eosinophilic granuloma. Pediatric gastrointestinal LCH, in contrast, is often devastating.

I’d like to start this day with something positive. But Russia just hit a school in Kyiv. The kids were in the shelter.

Russia has struck central Dnipro in broad daylight.

❗️A large business center is on fire, cars have been shattered, and people are reportedly trapped inside. There are casualties.

This is happening in the middle of the day, while people are simply at work.

‼️Russia continues its attacks on Ukraine 24/7. It targets offices, shopping malls, markets, and educational facilities daily. It must be held accountable for these attacks.

[Volodymyr Zelenskyy / Володимир Зеленський @ZelenskyyUa]

A Russian strike against the building of the National Academy of Sciences of Ukraine. A rescue operation is underway: crews are putting out the fire and searching for people who may have been trapped inside. All services are deployed. Today in Kyiv, a pharmaceutical company and gas stations were also attacked; in Dnipro, a business center; and in other cities and regions, civilian facilities, businesses, and communications infrastructure were targeted as well. Sadly, people have been killed… My condolences to their families and loved ones. Russia will definitely face a response to this. And every one of Ukraine’s partners must see from this terror, from these strikes, that supporting Ukraine means truly supporting people’s lives – supporting the principle that terror must never be normalized, anywhere. Russia must be held accountable for all of this and face real consequences. I thank everyone who helps Ukraine!

[Caolan @CaolanReports]

russia is systematically destroying European science and cultural heritage sites. They literally just hit this 19th century historic building in central Kyiv. It’s the headquarters of Ukraine’s National Academy of Sciences. Deplorable.

Russia intentionally bombs libraries, they destroyed 9 million books in Kharkiv recently.

Burning books has nothing to do with ‘territory’. Nazis did exactly the same thing for the same reason. To erase history.

[Hanna Lapsar @HLapsar]

russian drone operator deliberately aims a civilian in Kherson.
I just have no words for this…

[Volodymyr Zelenskyy / Володимир Зеленський @ZelenskyyUa]

Today, many were shocked by yet another video of the drone “safari” Russians are carrying out against civilians in Kherson. A Russian drone deliberately hunted down a man selling vegetables and detonated right next to him. The Russians even admitted to the crime, showing zero regret and openly boasting about tormenting people. The man was wounded in the blast. Every single day, ordinary people in Kherson face these Russian "safaris."

The world must see this. It must see every piece of evidence that Russia has gone mad and that its soldiers take pleasure in killing and abusing civilians. Without pressure on Russia, the dismantling of its capacity for aggression, and real security guarantees, it is simply impossible to imagine the world being able to coexist with this evil. We must remain resolute in defending life. We must act and support life in ways that force Russia to seriously think about peace rather than expanding the range of its drones.

This is not just about Ukraine. Russia’s campaign against human life must be stopped here in Ukraine before it spreads further. Finland and Kazakhstan, the Baltic states and Poland, the countries of the South Caucasus, Romania, and Moldova—all should work together to ensure real security guarantees and bring Russia’s war to an end. Peace is needed, which requires cooperation among everyone in the world who truly values peace. Thank you to everyone standing with Ukraine!
