Russian Security Council Deputy Chairman Dmitry Medvedev said on Saturday that his country has been "showing patience" when it comes to the use of nuclear weapons but warned that "any patience comes to an end", Azernews reports.

Medvedev stated that Western leaders, whom he called "pompous Anglo-Saxon imbeciles," think that Moscow is only talking about nuclear weapons but "will not cross the line" amid threats of Ukraine attacking deep into Russian territory.

The Russian official acknowledged that a decision on a nuclear strike is "an extremely difficult decision with irreversible consequences," but warned the West that if Moscow's patience ends, KIev will become "a giant gray melted spot on the site of the mother city of Russia."
