Serhiy Gaidai, head of the Luhansk regional administration, issued a video address warning residents that toxic fumes could cause “serious damage”. “Prepare face masks soaked in soda solution. When applied topically to the eyes, nitric acid causes severe damage with extensive necrosis of the cornea and conjunctiva, leading to vision loss, he said, urging those living near Rubizhne to stay indoors and seal their windows. “This chemical is very toxic and we do not know where the toxic cloud will go. “We will watch the wind and wait for rain,” he said. The alarming warning came as Ukrainian President Volodymyr Zelensky prepared to address the UN Security Council on increasing evidence of Russian war crimes against Ukraine. In comments to Ukrainian media, Zelensky promised that the Ukrainian authorities would set up an “internal mechanism” to locate Russian soldiers accused of committing war crimes against Ukrainian civilians, as Israel’s Mossad pursued Nazi fugitives around the world. “We will definitely deal with this,” he said, adding that “lists will be drawn up” of all those Russians accused of executing and torturing Ukrainian civilians. “There are people who really want to find these criminals,” he said. “Prosecutors of different nationalities will deal with all these crimes. They see a lot of evidence. And, unfortunately, the evidence will continue to come – there will be no less. There is still the Izyum ahead and many places where there is no access yet [for Ukrainian authorities]”We have no idea what happened there in the occupied Melitopolis, Berdyansk.” His comments came as the scale of Russian atrocities in the city of Bucha, a suburb of Kiev, left people shocked, with hundreds of innocent residents killed in the streets, some with signs of torture. Recent satellite images of the now-liberated city show that the bodies of slaughtered civilians had been swept into the streets for weeks before Ukrainian forces recaptured Russian territory, disproving Moscow’s shameless claim that its troops had not there. that they must have been Ukrainian forces. Russia’s Defense Ministry has claimed that the executions were “directed” by Ukrainian psychologists, a claim that was repeated in a full-scale propaganda campaign on Russian state television stating that Western intelligence services were behind the killings. In the face of these Russian denials on Tuesday, the Ukrainian media published an aerial video that allegedly recorded Russian troops in Bucha shooting directly at a man who was just passing by them on a bicycle. Ukrainian journalist Dmytro Komarov also shared footage from Bucha showing the consequences of Russia’s attacks on displaced Ukrainians. He said at least three civilian vehicles were found shot along an evacuation route, including a bus with a young couple inside and a vehicle where an elderly couple was killed.
