Russian President Vladimir Putin has said foreign states should understand: "It's best not to mess with us."

The premier said his armed forces were ready to meet any aggression and that the Ukraine crisis was the result of a refusal by Kiev to negotiate.

He added: "Thank God, I think no one is thinking of unleashing a large-scale conflict with Russia. I want to remind you that Russia is one of the leading nuclear powers."
