Johnson and the head of the EC urged to “remain vigilant in the coming hours” in the context of Ukraine

“The world must remain vigilant in the coming hours and days,” the British Prime Minister’s office said.

Johnson said the UK and the EU should continue to work with partners to develop a package of economic sanctions that would "punish Russia if it violates Ukraine's sovereignty."

In December, Russian President Vladimir Putin said that Russian troops were deployed on the territory of the country and did not threaten anyone.

The Kremlin emphasized that Russia was not going to attack anyone.

Russia's ambassador to Washington, Anatoly Antonov, has said that Russia needs good neighborly relations and is not interested in an attack.
