Russia has strongly criticized the United Kingdom after confirming that British-made drones have been used in Ukrainian attacks against targets inside Russia. Moscow warned that Britain would face consequences because of its support for Ukraine. The Russian Embassy in the UK accused London of deliberately increasing tensions in the Ukraine war. It said Britain was becoming directly involved by providing equipment that Ukraine uses to attack Russian targets. Russia warned that the deeper the UK becomes involved in the conflict, the greater the consequences could be. The UK government rejected Russia's warning and said it would continue supporting Ukraine. A spokesperson for the British Ministry of Defence said Britain stood "shoulder to shoulder" with Ukraine and remained determined to oppose Russian aggression. The British government said it would continue providing Ukraine with the equipment it needs to defend itself against Russia's invasion. The UK has been one of Ukraine's major military supporters since Russia launched its full-scale invasion in February 2022. The latest dispute focuses on drones built by two British companies. According to reports, these drones have been used by Ukraine in attacks against military and industrial targets inside Russia. Some of the targets reportedly included fuel facilities, warehouses and logistics centres. One of the companies affected by the attacks is Wildberries, a major Russian online retailer similar to Amazon. Ukraine has repeatedly targeted some of the company's logistics facilities, saying they are connected to Russia's military and industrial infrastructure. A military source confirmed to the BBC that British-made drones had been used in some of the attacks. Reports claim the strikes against Russian industrial and military facilities have caused significant economic damage. Russian Foreign Ministry spokeswoman Maria Zakharova also accused Ukraine of using drones containing British components and configurations to attack Russian territory. She said one such attack targeted a fuel depot in Russia's Rostov region. The Russian warning comes as the number of drone attacks between Russia and Ukraine continues to increase. During the latest overnight attacks, Russian officials said around 620 drones were directed toward the Moscow region. Russian air defences reportedly destroyed more than 180 of them. However, some people were injured, according to Russian officials. A Wildberries logistics facility near Moscow was also hit and caught fire. Regional authorities later said the fire had been put out. The company said the facility suffered minor damage. Ukraine also reported deadly Russian attacks. In the Zaporizhzhia region, at least two people were killed and four others were injured in Russian strikes, according to Ukrainian officials. Local authorities said hundreds of attacks had been carried out against settlements in the region during the previous 24 hours. The attacks followed another major wave of drone strikes on Saturday night. Ukrainian officials said hundreds of drones were launched toward Russia, with a large number reportedly aimed at Moscow. Russian authorities described the attack as one of the largest drone attacks on the capital in recent memory. Several people were reported killed across Russia. At the same time, Russian strikes against Ukraine killed at least seven people and injured more than 39 others, according to Ukrainian officials. The UK has continued increasing its military support for Ukraine. In April, Britain's Ministry of Defence announced plans to provide Ukraine with tens of thousands of drones, including long-range systems capable of striking targets at greater distances. The package was described as the UK's largest drone support package for Ukraine. The use of British-made drones inside Russia could therefore become another major source of tension between Moscow and London. Russia has repeatedly warned Western countries that supplying weapons to Ukraine makes them increasingly involved in the conflict. The UK, however, maintains that Ukraine has the right to defend itself against Russia's invasion. Britain says its military assistance is intended to help Ukraine protect its territory and resist Russian attacks. The latest exchange of warnings shows how the war is expanding beyond traditional front lines. Ukraine is increasingly using long-range drones to strike targets deep inside Russia, while Russia continues launching large-scale drone and missile attacks against Ukrainian cities and infrastructure. As both sides increase their use of long-range weapons, tensions between Russia and Western countries supporting Ukraine are also growing. Russia's latest warning to Britain suggests that Moscow may continue to pressure countries supplying weapons to Ukraine, while the UK appears determined to maintain its military support for Kyiv. The situation remains highly dangerous as Russia and Ukraine continue exchanging large numbers of attacks, with civilians and industrial facilities on both sides being affected by the ongoing war.
