Several other European officials expressed their alarm at the images from Bucha.
Roberta Metsola, the president of the European Parliament, said on Twitter that the images were “cold reality of Putin’s war crimes,” adding that the world “must be aware of what is happening.”
Latvia’s foreign minister, Edgars Rinkevics, condemned “genocide” and “war crimes committed against innocent civilians,” urging new sanctions against Russia and more military aid to Ukraine.
Analysts say that while war crimes cases can be brought before the International Criminal Court at the Hague, it would be extremely difficult to hold Russian leaders to account there because the court lacks enforcement powers. Prosecution at the International Court of Justice is also possible, but any ruling would need to be enforced by the United Nations Security Council, where Russia holds veto power.
American lawmakers said the reports from Bucha justified further assistance to Ukraine, with some calling for the provision of more surface-to-air missiles to help Ukrainian forces. Senator Rob Portman, Republican of Ohio, said that “we need to do more to help Ukraine, and we need to do more quickly.”
Sen. Chris Murphy, Democrat of Connecticut, said the images were evidence of war crimes committed by Russia. “Those that committed and authorized these acts will be damned by history and must be held accountable now,” he said.
