Ukraine has hit a major logistics hub of Russian online retailer Wildberries in Yekaterinburg, east of Moscow, continuing its three-week campaign of near-nightly strikes. At least 20 Wildberries warehouses have been attacked since July 18, sparking major fires, destroying entire warehouses of stock, and disrupting its vast logistics network across the world's largest country. According to Data Insight analyst Sergei Semko, goods destroyed by strikes on Wildberries warehouses in Moscow and Tambov regions alone were worth up to an estimated $2.9 billion.
