Russian forces are continuing their attempted push through Ukraine from multiple directions, while Ukrainians, led by President Volodymyr Zelenskyy, are putting up "stiff resistance," according to U.S. officials.
The attack began Feb. 24, when Russian President Vladimir Putin announced a "special military operation."
Russian forces moving from neighboring Belarus toward Ukraine's capital, Kyiv, have advanced closer to the city center in recent days despite the resistance, coming within about 9 miles as of Friday.
Russia has been met by sanctions from the United States, Canada and countries throughout Europe, targeting the Russian economy as well as Putin himself.

GOP points at Biden for Russian invasion in State of the Union response
Iowa Gov. Kim Reynolds implied Russia's attack on Ukraine is connected to a lack of leadership from President Joe Biden in the Republican response to the State of the Union address, saying Biden has "sent us back in time" to the 1970s and '80s, when the "Soviet army was trying to redraw the world map."
Reynolds said Biden has failed on his promise to make America respected around the world once more and criticized Biden for the lead-up to the invasion, including waving sanctions against Russia and "focusing on political correctness."
"Weakness on the world stage has a cost," Reynolds said. "... We can’t project strength abroad if we’re weak home."

'Free world is holding Putin accountable,' Biden says in SOTU address
In his first State of the Union address, President Joe Biden began by discussing the war in Eastern Europe and condemning Russian President Vladimir Putin’s invasion of Ukraine.
Biden invoked the strength of the Ukrainian people amid the attack, lauding the civilians who took up arms to defend their country and highlighting the work Ukrainian Ambassador to the U.S. Oksana Markarova has done on behalf of her people.
"She’s bright. She’s strong, and she’s resolved," Biden said as first lady Jill Biden hugged Markarova.

Many lawmakers in attendance showed their support for Ukraine by wearing color-coordinated outfits and lapel pins in blue and yellow.
Biden described the invasion as "premeditated and totally unprovoked," vowing, alongside NATO allies, to hold Putin accountable with sanctions on the Russian economy and Putin and the oligarchs themselves.
"When dictators do not pay a price for their aggressions, they cause more chaos," Biden said. “They keep moving.”
Biden announced that American airspace would be closed to all Russian flights and pledged $1 billion in direct assistance to help "ease suffering" in Ukraine.
The president also "made clear" that while American forces would not go fight in Ukraine, he has mobilized the military to protect NATO countries.
"The United States and our Allies will defend every inch of territory that is NATO territory with the full force of our collective power," he said.

Biden announces ban on Russian flights in US airspace
President Joe Biden in his State of the Union address announced the U.S. will ban Russian flights from its airspace, joining Canada and the European Union, which issued bans on Russian planes in their respective airspaces over the weekend.
"Tonight I am announcing that we will join our allies in closing off American air space to all Russian flights -- further isolating Russia -- and adding an additional squeeze on their economy," Biden said.
The ban will apply to "operations of all aircraft owned, certified, operated, registered, chartered, leased, or controlled by, for, or for the benefit of, a person who is a citizen of Russia," according to the Federal Aviation Administration. "This includes passenger and cargo flights, and scheduled as well as charter flights, effectively closing U.S. air space to all Russian commercial air carriers and other Russian civil aircraft."
The ban will be "fully effective" by the end of the day Wednesday, the FAA said.
