As it happened: Biden warns US intervention in Ukraine would mean WW3 - BBC News
The US president restated that his country's military would not directly intervene against Russia.
White House officials hosted a private Zoom briefing for about 30 influential TikTok creators to keep them informed of the latest US messaging regarding Ukraine, according to the Washington Post.

The briefing was conducted by White House Press Secretary Jen Psaki and National Security Council adviser Matt Miller. Several of the social media stars have since gone on to post about Ukraine.

The topic included the US "strategic goals in the region", according to the Post, such as how the US would respond to a Russian nuclear escalation and how US aid dollars are being spent to help Ukraine.

TikTok has been widely embraced by the Biden administration as a way to reach younger Americans who get much of their news from social media.
