Russian-controlled regions, including the occupied Crimea, also reported heavy attacks

Moscow has threatened the UK with “consequences” after reports that British drones have been used to strike targets on Russia’s mainland for the first time.

Ukraine used drones made by two UK companies as part of a so-called deep strike campaign, the Sunday Times reported.

“Britain stands shoulder to shoulder with Ukraine and we are committed to providing the equipment Ukraine needs to defend itself against Putin’s illegal invasion.

Russia should be in no doubt about the resolve of this government to stand against Russian aggression, in Ukraine and against the UK and our allies.”
