Invading Ukraine, Prime Minister Boris Johnson has warned, would be “disastrous” and a “painful, brutal, and bloody enterprise.”
The Prime Minister said the situation was “very dismal” but that conflict was not inevitable as the Foreign Office evacuated some embassy workers out of Ukraine.
He claimed that the UK was “leading on developing a package of economic penalties” against Russia and that it was supplying Ukraine with defensive weapons.
NATO is preparing to deploy forces.
In reaction to Russia’s continued build-up of forces, Nato allies are sending more ships and fighter jets to Eastern Europe to bolster defenses and increase deterrence.
Despite Russia’s denials of military activity, an estimated 100,000 troops have gathered near the border. The president of Nato has warned that a new confrontation in Europe is possible.
The move has been criticized by the Kremlin as heightening tensions. Russia views the alliance as a threat and is seeking formal assurances that it would not extend eastward, especially into Ukraine. However, the United States has stated that the problem at hand is Russian aggression, not Nato expansion.
Later, US President Joe Biden will hold a video conference with EU leaders, Nato Secretary-General Jens Stoltenberg, and Mr. Johnson.
“The intelligence is pretty clear that there are 60 Russian fighting formations on the Ukrainian border, and the strategy for a lightning war that might take out Kyiv is one that everyone can see,” Mr. Johnson said.
“We must make it obvious to the Kremlin and Russia that this would be a disastrous step.”
Mr. Johnson went on to say that the United Kingdom was “foursquare with the people of Ukraine.”

There are no plans for British combat soldiers to defend Ukraine, according to Downing Street.
There have been no explicit threats to British diplomats, according to officials, but around half of the staff in Kyiv will return to the UK. The US has urged relatives of its embassy workers to leave, citing the possibility of an invasion “at any time.”
The embassy relocation was termed as cautious, and nothing special in the last 24 hours is considered to have prompted the US and UK choices.
About 30 British diplomats remain in Ukraine, including the ambassador.
The British Embassy in Kyiv continued to operate, according to Foreign Secretary Liz Truss, but “it’s imperative that we ready for any scenario.”
She claimed the UK had a “very powerful package of sanctions ready to go” and that in the event of an incursion into Ukraine, Germany’s Nord Stream 2 gas pipeline to Russia should be canceled, adding that she was “very, very concerned” about Europe’s energy dependence on Russia.
Ms. Truss declined to elaborate on the source of the intelligence when asked about the UK’s suspicions that Russian President Vladimir Putin was trying to install a pro-Moscow figure to run Ukraine’s government.
She did, however, say: “We would denounce any attempt by Russia to influence democracy, destabilize Ukraine, or engage in false flag operations or sabotage. We’ll make a note of it.”
For the time being, EU personnel in Ukraine will remain in situ; EU foreign policy leader Josep Borrell has stated that he will not “dramatize” the tensions.
“My view is that they will fight,” the prime minister said, adding that he had visited Ukraine and knew the people.
“We also need to get a message that invading Ukraine, from a Russian standpoint, is going to be a difficult, brutal, and bloody business,” Mr. Johnson told reporters in Milton Keynes.
“I believe it is critical for Russians to recognize that this might be a new Chechnya.”
In the 1990s, Chechnya saw a major separatist conflict, with a decade of the ultimately fruitless battle for independence.
“I’ve got to tell you that I think the intelligence is fairly bleak at this moment,” Mr. Johnson responded when asked if an invasion was likely. There is undoubtedly a massive array of Russian forces, and we must take the required precautions.
“I don’t believe it’s unavoidable at this point; I believe common reason can still prevail.”
On Monday, he was scheduled to meet with overseas allies.

Russia previously grabbed Crimea in 2014, following violent anti-Russian riots in Ukraine that deposed the country’s pro-Russian president. Before Crimea voted to join Russia in a referendum that the West and Ukraine regarded unlawful, the Russian military seized control of the territory.
In a conflict that has cost an estimated 14,000 lives, Russian-backed separatists hold portions of eastern Ukraine near Russia’s borders. A 2015 peace agreement is still far from being implemented.
On Sunday, the UK Foreign Office accused Russian President Vladimir Putin of plotting to install a pro-Russian figure as Ukraine’s president, mentioning former Ukrainian MP Yevhen Murayev as a prospective candidate.
In an interview with the Reuters news agency, Mr. Murayev termed the charges “ridiculous.”
All travel to Crimea and two areas of eastern Ukraine, Donetsk oblast and Luhansk oblast, has been advised by the Foreign Office. It advises against traveling to the remainder of Ukraine unless absolutely necessary.
