Vladimir Putin has threatened to bomb the UK after Ukraine used British-made missiles to attack targets in Russia.
The Russian president said he was willing to “respond resolutely in a mirror way” is there is further escalation in the ongoing war.
His comments, in an address to the Russian people, came a day after Ukraine fired British Storm Shadow missiles at Russia.
Putin said: “We believe that we have the right to use our weapons against military facilities of the countries that allow to use their weapons against our facilities,” he said.
“And in case of escalation of aggressive actions, we will respond resolutely in a mirror way.”
