Russian forces have started military drills near Ukraine simulating the use of tactical nuclear weapons in response to what Moscow deems threats from western officials about increased involvement in the conflict. Vladimir Putin ordered the drills earlier this month in a move Russian officials said was a warning to the west not to escalate tensions further.
The Kremlin has particularly been angered by the French president, Emmanuel Macron, who floated the possibility of sending European troops to fight Russia in Ukraine, and by remarks from the UK foreign secretary, David Cameron, who said Ukraine had the right to use weapons supplied by London to target sites in Russia.
The Russian defence ministry published footage on Tuesday showing trucks carrying missiles to a field where launch systems had been prepared and troops at an airfield readying a bomber to carry a nuclear warhead.
The drills are taking place in Russia’s southern military district, headquartered in Rostov-on-Don, which borders Ukraine and includes parts of the country which Russia occupies.
