Ukraine said at least four people were killed today and a hospital was hit in a Russian missile attack in the Donetsk city of Avdiivka. This comes as Ukraine’s military said it has made advances in the devastated eastern city of Bakhmut, pushing back Russian forces, though Russia still retains control over the majority of the area. Earlier today, Russia said two senior military officers were killed in the eastern Donetsk region, which is home to Bakhmut. Over the weekend, The Washington Post reported recently leaked U.S. intelligence shows the head of the Russian mercenary Wagner Group, Yevgeny Prigozhin, offered in January to give Ukraine’s military the location of Russian troops to attack, if it pulled back Ukrainian forces from Bakhmut.

Meanwhile, Ukrainian President Volodymyr Zelensky is in the U.K., where the British government pledged long-range attack drones for Kyiv’s fight against Russia’s invasion. The visit comes as part of a whirlwind European tour over the weekend, where Zelensky met with Pope Francis at the Vatican and Italian leaders in Rome, followed by stops in Germany, which pledged nearly $3 billion in new military aid, and France, which promised more armored tanks.
