US people should leave Ukraine now, according to Joe Biden.

Due to escalating Russian military threats, US President Joe Biden has ordered all American citizens still in Ukraine to evacuate the country immediately.

Mr. Biden has stated that if Russia invades Ukraine, he will not send soldiers to rescue Americans.

“Things might get crazy rapidly” in the region, he said.

Despite massing more than 100,000 troops near the Ukrainian border, Russia has repeatedly denied any ambitions to invade the country.

However, it has recently launched large-scale military exercises with Belarus, and Ukraine has accused Russia of obstructing its access to the sea.

The Kremlin has stated that it intends to enforce “red lines” in order to prevent its former Soviet neighbor from joining Nato.

In the midst of the tensions, UK Prime Minister Boris Johnson declared on Thursday that Europe is facing its worst security crisis in decades.

The US State Department has advised Americans in Ukraine to leave as soon as possible.

Mr Biden told NBC News, “American citizens should leave now.”

“We’re up against one of the world’s largest armies.” It’s a whole different circumstance, and things might quickly spiral out of control.”

“There isn’t a scenario that would drive me to send troops to rescue fleeing Americans,” Mr Biden said when asked whether there was a scenario that would prompt him to send troops to rescue fleeing Americans. When the United States and Russia start shooting at each other, it’s a world war. We live in a completely different world these days.

Meanwhile, world leaders continued their frantic diplomacy to settle the current Ukraine issue.

Late Thursday, Russia and Ukraine stated that a day of discussions with French and German officials aimed at settling the separatist crisis in eastern Ukraine had failed to yield any results.

The current tensions are the result of Russia’s annexation of Ukraine’s southern Crimea peninsula eight years ago. Since then, Ukraine’s military has been fighting Russian-backed separatists in eastern Ukraine, close to Russia’s borders.

Earlier, UK Prime Minister David Cameron said he hoped “strong deterrence” and “patient diplomacy” could help resolve the crisis, but that the stakes were “extremely high.”

Mr Johnson told a joint press conference in Brussels with Nato Secretary-General Jens Stoltenberg that he did not believe Russia had made up its mind about invading Ukraine yet, but that the UK’s intelligence “remains gloomy.”

When asked if the UK would consider going further in its support for Ukraine, Mr Johnson said he would “examine what more we might feasibly offer,” including military support for an insurgency if Russia invaded.

“I don’t want to rule anything out,” he continued, “but at the time, we believe the package is the appropriate one.”

During a tense news conference with his British counterpart Liz Truss, Russian Foreign Minister Sergei Lavrov described the talks as “disappointing.”

Ms. Truss charged Russia for using “Cold War rhetoric.”

On Friday, Ben Wallace, the UK Defence Secretary, will meet with Sergei Shoigu, his Russian counterpart, in Moscow.

Mr Wallace revealed ahead of the trip that the UK was giving the Ukrainian government with more defensive equipment, such as body armor, helmets, and combat boots. He also stressed the importance of demonstrating that Nato members “will not be pushed around by threats.”

Meanwhile, as Russia prepares for naval exercises, Ukraine accuses Russia of obstructing its access to the sea.

Russian soldiers have totally blocked the Sea of Azov, and the Black Sea is almost completely sealed off, according to Ukrainian Foreign Minister Dmytro Kuleba.

The Black Sea and the Sea of Azov, both to the south of Ukraine, will host Russian naval drills next week. Russian coastline warnings have been issued, citing missile and gunnery exercises.

The “unprecedentedly broad region where the manoeuvres would be conducted renders navigation in both seas nearly impossible,” according to Ukraine’s foreign ministry, while Defense Minister Oleksiy Reznikov tweeted that Russia has shut the international waters of the two seas.

The naval drills off Ukraine’s southern frontier come on top of the ten-day military drills already underway in Belarus, to Ukraine’s north.

There are concerns that if Russia tries to invade Ukraine, the exercises will bring Russian troops closer to Kyiv, making an attack on the city easier. After the drills, Russia says its troops will return to their permanent bases.

Ukraine has begun its own 10-day military drills, albeit little specifics have been released.
