Homes destroyed by Russian shelling in Slovyansk, eastern Ukraine, in early June. Fighting continued on Tuesday in the streets of Severodonetsk, the city in the Luhansk region of eastern Ukraine where Russia is now concentrating its firepower. European officials accused Moscow of weaponizing food supplies. The Kremlin pledged to allow grain exports if Ukraine demines access to Black Sea ports, while Kyiv expressed distrust in such promises. Russia’s Foreign Ministry said it would impose sanctions on dozens of U.S. nationals, including government officials and corporate executives, in response to U.S. sanctions.
