Russia and Ukraine got in a Twitter feud

Russia and Ukraine engaged in a brief skirmish this morning — on Twitter, in English.

The beef: The countries argued over the nationality of Anna Yaroslavna, the queen consort of France from 1051 to 1060. She was born in Kievan Rus — a connected group of Slavic tribes from which some modern nations, including both Russia and Ukraine, claim their cultural ancestry. So to Ukrainians, she's "Anne of Kiev," and to Russians, she's "Anne of Russia."

Why it matters: It's just another arm of the all-out propaganda war between Russia and Ukraine following Russia's illegal seizure of Crimea. Plus, the statement "comply with int law" between two countries is all the more devastating when it's delivered with a Benedict Cumberbatch GIF.

We may be "at the brink" of a global pandemic, warns a top U.S. public health official, as cases continue to spread despite containment efforts. Meanwhile, the global economy is being affected, including the tech manufacturing industry.

The big picture: COVID-19 has now killed more than 2,000 people and infected over 75,000 others, mostly in mainland China, where the National Health Commission announced 136 new deaths since Tuesday.
