Biden and Putin to speak; US orders most embassy staff out of Ukraine

• US, other Western states warn war in Ukraine could ignite at any moment.
• Washington orders most of its embassy staff to leave Ukraine.
• Moscow has repeatedly disputed Washington's version of events.

WASHINGTON/MOSCOW: US President Joe Biden and his Russian counterpart Vladimir Putin will speak on Saturday as the United States and other Western nations warned a war in Ukraine could ignite at any moment.

Washington ordered most of its embassy staff to leave Ukraine on Saturday, adding to its call this week for private citizens to leave the country as soon as possible.

Additionally, about 150 troops from the Florida National Guard who are in Ukraine to help train Ukrainian forces are leaving the country as the threat of a Russian invasion increases, two US officials told Reuters. 

Russia's military buildup near Ukraine and a surge of military activity has fuelled fears that Russia could invade. Russia denies having any such plans.

Putin requested the telephone call between the leaders to take place on Monday, a White House official said, but Biden wanted to conduct it sooner as Washington detailed increasingly vivid accounts of a possible attack on Ukraine.

Australia, New Zealand, Germany, Italy and the Netherlands on Saturday joined countries urging their citizens to leave Ukraine. Washington said on Friday that a Russian invasion, including a possible air assault, could occur anytime.

Moscow has repeatedly disputed Washington's version of events, saying it has massed more than 100,000 troops near the Ukrainian border to maintain its own security against aggression by NATO allies.

Russia, which has accused Western nations of spreading lies, meanwhile said on Saturday it had decided to "optimise" its diplomatic staff numbers in Ukraine, fearing "provocations" by Kyiv or another party.

Moscow did not say whether that meant a reduction in staff numbers but said the embassy and consulates in Ukraine continued to perform their key functions.

US Secretary of State Antony Blinken said Washington would impose swift economic sanctions if Moscow invades.

"I continue to hope that he will not choose the path of renewed aggression and he'll chose the path of diplomacy and dialogue," Blinken told reporters after a meeting with Pacific leaders in Fiji. "But if he doesn't, we're prepared."

In a phone call later with Blinken, Russia's top diplomat Sergei Lavrov accused the United States and its allies of waging a "propaganda campaign" about Russian aggression towards Ukraine, the Russian foreign ministry said.

Russian Defence Minister Sergei Shoigu and his US counterpart Lloyd Austin also talked by phone on Saturday, Interfax news agency and the Pentagon said.

Security guarantees

Putin, jostling for influence in post-Cold War Europe, is seeking security guarantees from Biden to block Kyiv's entry into NATO and missile deployments near Russia's borders.

Washington regards many of the proposals as non-starters but has pushed the Kremlin to discuss them jointly with Washington and its European allies.

Still, Biden has long believed that one-on-one engagement with Putin may be the best chance at a resolution. Two calls in December between Biden and Putin produced no breakthroughs but set the stage for diplomacy between their aides. The two leaders have not spoken since, and diplomats from both sides have struggled to find common ground.

Four-way talks in Berlin between Russia, Ukraine, Germany and France on Thursday made no progress.

Putin also plans to speak with French President Emmanuel Macron on Saturday, according to Russia's TASS news agency.

German Foreign Minister Annalena Baerbock said on Saturday that the crisis between Russia and Ukraine was escalating, but Germany was making all efforts to find a diplomatic solution.

Gathering forces

Biden's national security adviser, Jake Sullivan, told reporters on Friday that US intelligence believes a rapid assault on Kyiv is possible and that Putin could order an invasion before the Winter Olympics in China end on Feb. 20. He added that it remains unclear whether such a command has been given.

He said the Russians had gathered sufficient troops near the border to invade the country and that they may initiate an aerial bombing.

Russia's Deputy UN Ambassador Dmitry Polyanskiy accused Washington of mounting a "panic campaign".

Ukrainian officials have tried to tamp down Washington's assessment an invasion could be imminent.

Several thousand Ukrainians rallied in Kyiv on Saturday to show unity amid fears of an invasion, as Ukraine's leader told people not to panic and pushed back against what he said was a glut of bleak war predictions being reported in the media. 

Still, Washington planned to send 3,000 extra troops to Poland, Ukraine's western neighbor, in coming days to try to help reassure NATO allies, four US officials told Reuters. They are in addition to 8,500 already on alert for deployment to Europe if needed. 

Meanwhile, Russian forces gathered north, south and east of Ukraine.

More than 30 ships from the Russian Black Sea fleet have started training exercises near the Crimea peninsula as part of wider navy drills, RIA news agency reported on Saturday. 

Ahead of the talks with Putin, Biden spoke about the crisis with the leaders of Britain, Canada, France, Germany, Poland and Romania, as well as the heads of NATO and the EU. As the tensions have risen in recent weeks, Washington has sought to ensure that its allies would respond in unison if Russia does invade.
