Moscow has accused London of deliberately escalating the Ukraine conflict by supplying weapons used to strike Russian territory.

The UK is deliberately escalating the Ukraine conflict and acting as an accomplice to Kiev’s terrorist attacks, Russia’s embassy in London has said, warning that Britain will be held accountable for its actions.

The statement comes after a Sunday Times report claiming that Ukrainian forces have used drones supplied by two British manufacturers for long-range attacks inside Russia over the past six months.

Multiple Ukrainian military sources told the newspaper that British UAVs had been deployed against industrial and military targets, including oil refineries in Volgograd and Yaroslavl.

The Russian Embassy responded on Monday, saying that the report confirms that “London is deliberately opting for an escalation of the Ukraine crisis, while hypocritically professing a desire for peace.”

“In doing so, the United Kingdom is acting as an accomplice and co-perpetrator of the bloody crimes and terrorist attacks committed by Ukrainian neo-Nazis, seeking to contain Russia and inflict maximum damage on it by proxy,” the embassy wrote, warning that “London’s actions will inevitably carry consequences for which it will have to answer.”

“The deeper its involvement in the conflict and the greater its support for Kiev’s terrorist machinery, the higher the price it will pay,” the statement concluded.

The British House of Commons has been one of Kiev’s most active military backers since the escalation of the conflict in 2022. In June, London pledged to provide Ukraine with 150,000 drones by the end of the year and has already supplied long-range ‘Storm Shadow’ cruise missiles, which have also been used for attacks inside Russia. Several Ukraine-linked drone production facilities are also operating on British soil.

Kiev has sharply intensified its long-range attacks in recent months, launching hundreds of UAVs at a time against Russian territory. Moscow says the strikes have increasingly hit energy infrastructure, residential areas and other civilian sites, killing and wounding dozens of civilians, including children.

Russia has responded by stepping up its own missile and drone strikes against Ukraine’s military-industrial facilities, logistics centers and infrastructure supporting its armed forces.

Moscow has repeatedly argued that Western weapons deliveries, intelligence sharing and targeting assistance make NATO countries direct participants in the conflict. Last week, Foreign Minister Sergey Lavrov warned that Russia would continue to adopt “much harsher methods to destroy everything that enables the West to fuel Kiev’s war machine.”

Russian officials have also warned that Ukraine-linked weapons manufacturing facilities scattered across Europe could be regarded as legitimate military targets.
