WASHINGTON, Jan 26 (Reuters) - The United States on Thursday stepped up sanctions against the Wagner Group, labeling the Russian mercenary company fighting in Ukraine as a transnational criminal organization responsible for widespread human rights abuses. The U.S. Treasury Department, as part of action targeting dozens of people and entities in an effort to degrade Russia's ability to wage the war, said it designated Wagner Group as a "significant transnational criminal organization" on Thursday. It had previously designated Wagner under its Russia and Ukraine sanctions programs. "These images were gathered in order to enable Wagner combat operations in Ukraine," Treasury said. He said the United States assesses Wagner has about 50,000 personnel deployed to Ukraine, including 40,000 convicts recruited from Russian prisons.
