British-made drones have been deployed to strike military and industrial targets inside mainland Russia for the first time. According to the BBC, these weapons, produced by two separate UK firms, have successfully hit refineries and warehouses belonging to the online retailer Wildberries. The strikes are reported to have caused over £35 billion in economic damage. While UK-manufactured Storm Shadow missiles were previously used in the conflict, this new phase of drone deployment is described as having a more decisive impact. A military source confirmed to the BBC that UK drones were utilized. The UK Ministry of Defence has stated its support for Ukraine is 'unwavering' and that it will provide the equipment necessary for Ukraine to defend itself against Russia's invasion. In April, the MoD announced the supply of tens of thousands of drones, including long-range strike devices, in its largest-ever package. Russian Foreign Ministry spokeswoman Maria Zakharova had previously acknowledged the use of drones with UK components to attack Russian territory, including a fuel depot in the Rostov Region.
