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.

Russia says negotiations will begin after 'democratic order' restored
Russia will begin negotiations again once "democratic order" is restored in Ukraine, Russian Minister of Foreign Affairs Sergey Lavrov said Friday, amid an ongoing invasion of the neighboring country.
"We are ready for negotiations, at any moment, as soon as the Armed Forces of Ukraine respond to the call of our president to cease resistance and lay down their arms. No one intends to attack them," Lavrov said during a televised meeting in Moscow with pro-Russian separatist leaders from eastern Ukraine.
Lavrov's comments come as Russian forces attacked Ukrainian troops in Kyiv on Friday morning, as the fighting drew closer to the capital's city center.

Gunfire, explosions heard within Kyiv as fighting draws near
ABC News' team in Kyiv saw a large explosion and heard intense gunfire in the distance early Friday afternoon.
The crackles of gunfire appeared to be several miles north of the center of the Ukrainian capital, but still well within the city limits.
Ukrainian authorities have told residents in the northern suburb of Obolon to take shelter and prepare for imminent military action. The area is a 10-minute drive from Kyiv's center.
The capital remains on edge as Russian forces draw near. Earlier, Ukrainian troops were seen hurriedly moving with ammunition to set up positions in the city center as air-raid sirens rang out.
Thousands of people have tried to leave Kyiv and head west to the Polish border, with some spending hours stuck in long traffic jams.
The Ukrainian military said it has distributed 18,000 assault rifles to territorial defense volunteers in the capital. It has also begun handing out weapons to civilians who want to fight and has called on healthy men over the age 60 to join the defense force, if they wish.
