Ukrainian President Volodymyr Zelensky is asking the U.S. and other allies for the rapid delivery of more heavy weaponry, saying it’s critical to the fight against Russia’s advance in the eastern Donbas region. Ukraine’s military claims its soldiers continue to hold ground in an industrial part of Severodonetsk while battling Russian troops street by street. Elsewhere, Ukraine says three civilians were killed and five wounded by Russian shells falling on the city of Kharkiv. Meanwhile, a court in Russian-controlled eastern Ukraine has sentenced two Britons and a Moroccan to death, accusing them of being “mercenaries” for Ukraine’s army.
