Ukrainian President Volodymyr Zelenskyy accused the Russians of gruesome atrocities in Ukraine and told the U.N. Security Council on Tuesday that those responsible should immediately be brought up on war crimes charges in front of a tribunal like the one established at Nuremberg after World War II. Over the past few days, grisly images of what appeared to be intentional killings of civilians carried out by Russian forces in Bucha and other towns before they withdrew from the outskirts of Kyiv have caused a global outcry and led Western nations to expel scores of Moscow’s diplomats and propose further sanctions, including a ban on coal imports from Russia. Zelenskyy, speaking via video from Ukraine to U.N. diplomats, said that civilians had been tortured, shot in the back of the head, thrown down wells, blown up with grenades in their apartments and crushed to death by tanks while in cars. “They cut off limbs, cut their throats. Women were raped and killed in front of their children,” he said. He asserted that people’s tongues were pulled out “only because their aggressor did not hear what they wanted to hear from them.” Zelenskyy said that both those who carried out the killings and those who gave the orders “must be brought to justice immediately for war crimes” in front of a tribunal similar to what was used in postwar Germany.

Others simply surveyed the destruction. In Borodyanka, northwest of Kyiv, 25-year-old, Dmitriy Yevtushkov searched the rubble of apartment buildings and found that only a photo album remained from his family’s home. In the besieged southern city of Mykolaiv, a passerby stopped briefly to look at the bright blossoms of a shattered flower stand lying among bloodstains, the legacy of a Russian shell that killed nine. The onlooker sketched out the sign of the cross in the air, and moved on. Associated Press journalists in Bucha have counted dozens of corpses in civilian clothes and interviewed Ukrainians who told of witnessing atrocities. Also, high-resolution satellite imagery from Maxar Technologies showed that many of the bodies had been lying in the open for weeks, during the time that Russian forces were in the town.
