Russia-Ukraine updates: US to ban Russian carriers from its airspace

Biden will announce the news in his State of the Union address, a source said.

Russian forces are continuing their attempted push through Ukraine from multiple directions, while Ukrainians, led by President Volodymr Zelenskyy, are putting up "stiff resistance," according to U.S. officials.

The attack began Feb. 24 as Russian President Vladimir Putin announced a "special military operation."

Russians moving from Belarus towards Ukraine's capital, Kyiv, don't appear to have advanced closer towards the city since coming within about 20 miles, although smaller advanced groups have been fighting gun battles with Ukrainian forces inside the capital since at least Friday.

Russia has been met by sanctions from the U.S., Canada and countries throughout Europe, targeting Russia's economy and Putin himself.

Pushilin's comments come after the separatists yesterday announced mass evacuations and warned of an imminent Ukrainian "offensive" amid fears Russia is moving to stage a pretext to attack Ukraine, cloaking it as aid to the separatists.
