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.
Ukraine said it wanted a ceasefire and Russian withdrawal, while the Kremlin said it would not announce its position. Russia's negotiators have talked of striking a deal that's in the interests of both sides.

Russian advance frustrated by resistance: US official
Russian forces are frustrated by their slow advance, but that could lead them "to be more aggressive and more overt in both the size and scale of their targeting of Kyiv," a senior U.S. defense official said Monday, implying less discriminate attacks with more danger to civilian populations.
The Russians heading south to Kyiv continue to be slowed by fuel shortages and stiff Ukrainian resistance and have only moved about three miles since Sunday, leaving them about 16 miles away from the capital city, the official said.

"We believe they want to encircle Kyiv and it's possible that they could adopt siege tactics there," the official warned. On Sunday the same official said there were indications Russian forces were adopting siege tactics around the city of Chernihiv in northern Ukraine.
So far, the Russians have fired more than 380 missiles, the official said.

Putin has committed about 75% of the more than 150,000 forces he had arrayed at the border to the invasion inside Ukraine, according to the official.
There's no indication Belarusian forces are involved or are preparing to join Russia in the invasion, and Russia has not placed nuclear weapons in Belarus, according to the official.
