JUST IN: Tension As New Intelligence Suggests Russia Could Launch Attack On Ukraine Before The End Of Olympics

The US and its allies have new intelligence that suggests Russia could launch an attack on Ukraine even before the end of the Olympics, multiple sources familiar with the matter told CNN. 

Prior to the start of the Olympics earlier this month, Deputy Secretary of State Wendy Sherman suggested that the Winter Games, which are hosted by China, could impact Russian President Vladimir Putin's thinking about the timing of a potential invasion. 

Putin traveled to Beijing for the beginning of the Olympics and met with Chinese President Xi Jinping. The two released a lengthy pact pledging no limits to their cooperation.

Blinken told reporters at the joint news conference Friday that the US was "continuing to draw down our embassy" in the Ukrainian capital of Kyiv and "will continue that process."

"And we've also been very clear that any American citizens who remain in Ukraine should leave now," he added.

In Washington, the White House convened a meeting with several Cabinet members and senior national security officials in the Situation Room on Thursday night to discuss Russia's ongoing military buildup near Ukraine, two officials familiar with the matter told CNN. 

There have been several Situation Room meetings in recent weeks and months to discuss the brewing crisis, one of the sources said, but the meetings have grown more urgent in recent days as Russia has continued to move forces, weapons and logistical equipment into the area and increased troop readiness. 

Biden will hold a call with other world leaders at 11:00 a.m. ET Friday on the situation in Ukraine, a White House official told CNN. The leaders of Canada, the United Kingdom, France, Germany, Italy, Poland, Romania, NATO, the European Commission and the European Council will be on the call, according to the official.
