It's after 7:30 p.m. in Ukraine. Here's what's happened on Saturday so far.
Finland makes moves toward NATO: Finland's President Sauli Niinistö told Russian President Vladimir Putin on Saturday that the Nordic nation will decide "to seek NATO membership in the next few days," Niinistö's office said in a statement.
Putin said it would be a "mistake," according to the Kremlin, adding "it may have a negative impact on Russian-Finnish relations." Russia previously warned Finland, which it shares an 800-mile border with, that it “will be forced to take retaliatory steps, both of a military-technical and other nature, in order to stop the threats to its national security that arise in this regard,” according to its foreign ministry.
Russia also suspended power exports to Finland, Finnish operator Fingrid confirmed to CNN on Saturday. Fingrid brushed off the cut, as Russian electricity amounts to a small fraction of the country’s total consumption.
Programming note: CNN's Dana Bash will interview the Finnish president on Sunday's "State of the Union" at 9 a.m. ET.
GOP senators in Kyiv: A delegation of Republican US senators, led by Minority Leader Mitch McConnell, met with Ukrainian President Volodymyr Zelensky.
Zelensky said on his Instagram account that the visit "is a strong signal of bipartisan support for Ukraine from the United States Congress and the American people."
The visit comes as Congress has been trying to pass a roughly $40 billion aid bill that would provide Ukraine with military and humanitarian assistance.
Combat moves: The Ukrainian military said Russian forces are retreating from the northern Kharkiv region. A fierce counterattack has taken back a number of villages in the area east of Kharkiv.
But a Ukrainian lawmaker called on the United States to provide air defense systems and fighter jets to Ukraine, saying that the situation on the battlefield is "far worse" than it was at the beginning of the war.
Meanwhile, satellite imagery and firsthand testimony have provided a fuller picture of the multiple and disastrous efforts by Russian forces to cross the Siverskyi Donets River in eastern Ukraine over the past week. New video and analysis of drone and satellite imagery show that the Russians may have lost as many as 70 armored vehicles and other equipment in attempting to cross the river early this week. Their goal was to try to encircle Ukrainian defenses in the Luhansk region, but it failed.
Azovstal families appeal for extraction: The relatives of Ukrainian soldiers still holed up in Mariupol's Azovstal plant are appealing to Chinese President Xi Jinping to act as a mediator to help extract their loved ones, following a similar plea to Turkish President Recep Tayyip Erdoğan.
"Our children are in hell," one father said at a press conference in Kyiv.
A Ukrainian fighter inside the plant told Ukrainian TV about horrific conditions for the wounded, saying that "fighters are simply lying without limbs, without arms, without legs." Conditions are unsanitary and there is no medicine, the solider said.
Ukraine's deputy prime minister said the government would welcome the prospect of Turkish or Chinese mediation in helping to arrange the evacuation of wounded soldiers from the Azovstal complex in Mariupol.
