Russia-Ukraine updates: Putin says 'certain positive movements' in negotiations

Deb Parry, who is currently leading Save the Children’s team in Poland, told ABC News she has never seen anything like the outpouring of help on the Polish border.

“I’ve worked for Save the Children for 30 years and I’ve never seen anything like it. There’s a phenomenal amount of aid being sent. Everything these families could possibly need.”

“They even sent skis!” she exclaimed.

The donations are piling up all over Poland and being dropped near the crossings and reception centers throughout the country. Piles of skis and snowboards were stacked up at Dolhobyczow, a village near the Ukraine border.

“I’m not sure why people think they need skis,” Parry said.

Because of this effort by local communities, Save the Children can focus on things other than the distribution of necessities. More than 700,000 refugees have streamed across the Poland border since Russia invaded Ukraine on Feb. 24 -- almost all of whom are women and children.

Save the Children is helping parents talk to their children about war. They have teamed up with the telecom companies providing SIM cards and hand out leaflets with information for how best to cope in these trying conditions.

“It’s important to keep children in some sort of a routine,” Parry explained, adding that parents or caretakers need to be careful about what they expose children to.

“Don’t have the news on all the time,” she said.

Representatives from Facebook and Twitter provided updates about their services after the Russian government announced it would block both services.

Twitter security chief Yoel Roth said the company has not confirmed its services are completely disabled in Russia during a public panel Friday evening.

Meta, Facebook's parent company, put out a statement contending, "despite the Russian government’s announcement that they will be blocking Facebook, we are working to keep our services available to the greatest extent possible."

Meta added that "ads targeting people in Russia will be paused, and advertisers within Russia will no longer be able to create or run ads anywhere in the world, including within Russia."

As tensions rise between the United States and Russia over the conflict in Ukraine, national security officials will appear on Capitol Hill March 8 at 10 a.m. for the House Intelligence Committee's annual worldwide threats hearing.

The public portion of the hearing will include CIA Director Bill Burns, FBI Director Chris Wray and Director of National Intelligence Avril Haines. Burns notably traveled to Moscow last fall reportedly to confront Russian President Vladimir Putin over the troop buildup on Ukraine's borders and his plans to invade the country.

Publicly and privately, lawmakers have criticized the Biden administration over the pace and scope of intelligence sharing with Ukraine over the last week.

The officials will also testify before the Senate later in the week.

Ukrainian President Volodymyr Zelenskyy angrily denounced NATO in a televised address Friday over its refusal to impose a no-fly zone over Ukraine.

"Knowing that new strikes and casualties are inevitable, NATO has consciously taken the decision not to close the sky over Ukraine. All the people who will die from this day, will die also because of you," he said.

Zelenskyy accused NATO of creating a narrative "that the closure of the sky will allegedly provoke a war with Russia."

"It's a self-hypnosis of those who are weak, unconfident inside, though it can possess weapons a lot bigger than we do. You should have thought about people, about humanity," he said.

Zelenskyy said the alliance did agree to purchase 50 tons of fuel, but the president scoffed at the move.

"I don't know who you can defend and whether you are capable. You can't pay off with liters of diesel fuel for the liters of our blood, shed for our common Europe, for our common freedom, for our joint future," he said.
