The U.S. Treasury Department announced sanctions against a number of individuals and entities associated with the Wager Group in Russia and across the world in an effort to "degrade the Russian Federation’s capacity to wage war against Ukraine," the department said in a statement.

The U.S. designated Russia's Wagner Group a "transnational criminal organization," not just for the alleged atrocities it has committed during Russia’s invasion of Ukraine, but also for its alleged human rights abuses in African countries like the Central African Republic.

The U.S. believes the Wagner Group has 50,000 people fighting in Ukraine, including 40,000 convicts, according to the White House. The group's leader is Russian President Vladimir Putin's ally Yevgeniy Prigozhin, who was already facing several U.S. sanctions.

Last week, the White House first announced the U.S. would take this step.

At least 15 missiles fired at Kyiv on Thursday were shot down, officials said.

One person was killed and two were wounded after part of a missile fell in the Holosiivskyi District of Kyiv, Mayor Vitaliy Klychko said. The missile hit a residential building, he said.

Air raid sirens began sounding just before sunrise in the capital. Some residents fled to shelters, including Kyiv's metro stations.

A missile also struck Vinnytsia, the local governor said. No casualties were immediately reported there.

Air raid sirens went off across Ukraine as Russia launched multiple missiles from the east and south. Some were shot down, according to Andriy Yermak, head of the president's office.

Airborne forces last night shot down all 24 unmanned aerial vehicles launched by Russia. At least 15 of those were shot down in or around Kyiv, according to the local authorities. No casualties or impacts were reported.

U.S. President Joe Biden made an unannounced visit to war-torn Ukraine on Monday, arriving in Kyiv as Washington signals its ongoing support ahead of the one-year anniversary of Russia's invasion.

Biden's visit came ahead of a planned meeting with NATO allies in Poland. He is expected to give a speech at the Royal Castle Arcades in Warsaw on Tuesday evening to offer an appraisal of international support during the first year of the war and to address "how we will continue to stand with the people of Ukraine for as long as it takes," White House spokesperson Karine Jean-Pierre said in a statement earlier this month.

Biden also plans to meet in Poland with leaders of the Bucharest Nine, a group of eastern NATO allies formed in 2015 in response to Russia's annexation of Ukraine's Crimean Peninsula.

Ukrainian President Volodymyr Zelenskyy made a dramatic visit to the United States in December, his first known international trip since the Russian invasion began in February 2022. Zelenskyy met with Biden at the White House in Washington, D.C., before addressing members of U.S. Congress on Capitol Hill.
