False and misleading information about the Russian invasion of Ukraine has spread rapidly on social media since Russian forces launched a military assault in the pre-dawn hours of Feb. 24. Here’s a roundup of claims related to the Ukraine-Russia conflict analyzed by the USA TODAY Fact Check team.

British website The Telegraph is reporting that Russia is using mobile crematoriums in Ukraine in bid to hide its losses. But the accompanying video footage of a crematorium actually dates from 2013. It was posted by a Russian incinerator construction company and is not footage from the ground. The use of mobile crematoriums by Russians during the current war in Ukraine is yet to be verified. We tell you more in this edition.

The viral image of children waving off troops dates back to 2016. It does not depict the current conflict between Ukraine and Russia. Our ruling Social media posts claim that a viral image, which shows two young children holding hands and saluting troops, was captured in Ukraine in 2022. But the photo traces back to 2016. We rate these posts False.

Social media posts feature an alleged CNN tweet that claims American actor Steven Seagal took up arms alongside Russian special forces in Ukraine. But CNN said the tweet — which includes an image of Seagal in fatigues and carrying a weapon — is fake, and his representatives also rejected the claim, saying the actor wants peace for both countries.

5 fakes of the war in Ukraine including: #1. “Celebrating the war”. Video claims to show Russian soldiers dancing before heading to the frontline in Ukraine. In reality, dancing was in Tashkent, Uzbekistan. #2. “Russian jets launching attacks” – False. Video is from video game “Arma-3”. #3. “Formation of jets over an urban areas” – Not from war in Ukraine. Video is from a 2020 Moscow air show. #4. “German news shows hundreds of Russian soldiers allegedly parachuting over the Ukrainian city of Kharkiv” – False. Old video from Russia (2016).

There is no evidence of Vesela Hora being shelled by the Ukrainian army

This claim has been shared in several waves in at least three countries, but it is nothing more than an attempt at inducing panic

Ukraine haven’t trespassed Russian border and didn’t send commandos or APS’s across the border

Putin claims: “Does Ukraine need to be denazified” – false, “Is Russia’s attack a defense case under the UN Charter?” – false, “Was there a ‘genocide” in Ukraine?” – false. Russia has so far failed to provide any evidence in their claims.

Many posts on social media claiming to pertain to the current conflict in Ukraine are in fact videos and photos of different events in other regions that happened several years ago. We tell you more in this edition of Truth or Fake.

There are no U.S.-run biological weapons labs operating in Ukraine. The U.S. Defense Department and the Ukraine Ministry of Health have had a partnership since 2005 to improve public health laboratories and prevent the threat of outbreaks of infectious diseases. That effort is part of the Cooperative Threat Reduction Program, which began in 1991 to reduce the threat of existing weapons of mass destruction programs in former Soviet Republics. Our ruling A social media user tweeted that Russia was targeting U.S.-run biolabs in its invasion of Ukraine. That account was soon suspended by Twitter. There are no U.S.-run biolabs in Ukraine. The country is one of many former Soviet Union republics, and other countries, partnering with the Defense Department as part of the Cooperative Threat Reduction Program. It’s the latest claim in a series of disinformation efforts by the Russians, an expert told PolitiFact. While the U.S. may provide funding to upgrade or build labs in other countries, the labs are run by the partnering nations and the program’s goal is to prevent biological threats, not create them. We rate this claim False.

Despite multiple claims of a Ukrainian genocide against ethnic Russians, there is no evidence to support it. International bodies that include Russian representatives report that civilian deaths have plummeted since 2014. Russia’s ambassador to the U.S. relied on misleading and outdated evidence to back the claim. Our ruling Putin said ethnic Russians in Ukraine face genocide. His ambassador provided misleading evidence, and international observers found no activities to support the claim. Civilian deaths have plummeted to less than 1% of what they were in 2014. We rate this False.

Social media posts claim a photo of a wounded child shows a victim of Russia’s invasion of Ukraine. This is false; the picture is from 2018 and was taken in Syria.

Social media posts claim a photo of a man in samurai regalia shows Japan’s ambassador to Ukraine, saying he chose to stay and fight invading Russian forces. This is false; the image pictures Ukraine’s ambassador to Japan, who tweeted it prior to the invasion.

A video of military planes flying in formation over residential buildings has been viewed hundreds of thousands of times in posts that claim it shows Russian fighter jets entering neighbouring Ukraine in February 2022. The posts circulated online within hours of Russian President Vladimir Putin unleashing a full-scale ground invasion and air assault on Ukraine. The footage, however, has been shared in a false context. It has circulated since at least 2020 in social media posts about rehearsals for a Victory Day air show in Russia.

After Russian President Vladimir Putin launched a full-scale invasion of Ukraine, dramatic footage of a huge explosion was viewed tens of thousands of times in social media posts that claimed it shows buildings destroyed by Russian air strikes. In fact, the video shows a deadly blast that ripped through the Lebanese capital Beirut in August 2020.

Disinformation is part and parcel of the approach to war as seen in the Russian invasion of Ukraine.

Ukrainian Armed Forces are holding back the Russian aggressor’s offensive.

Ukrainians did not shoot at the Russian border checkpoint.

The Ground Forces of the Armed Forces of Ukraine have denied this information. The Ukrainian military did not put down their weapons and did not side with the Luhansk People’s Republic.
