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.

U.S. Secretary of State Antony Blinken crossed the border into Ukraine Saturday after meeting with Ukrainian Foreign Minister Dmytro Kuleba at the Korczowa Border Crossing Point.

"The entire world stand with Ukraine," Blinken said, and Kuleba added that he hopes Ukrainians will see this as a "clear manifestation that we have friends who literally stand by us."

Blinken said the sanctions imposed so far against Russia are "producing very, very concrete results" and that the pressure will "grow" until this "war of choice is brought to an end."

When asked directly about helping Kuleba with more firepower, Blinken said, "the support for Ukraine not only has been unprecedented, not only is going to continue, it's going to increase."

Kuleba said Ukraine "appreciates" sanctions that have been announced in the last week, but that more economic and political pressure and "necessary weapons," would "save many lives in Ukraine... many sufferings will be avoided."

Kuleba also said that they are “satisfied" with already arranged supplies of anti-tank weapons and ammunition, but that “it’s no secret” they still want fighter jets and air defense systems.

He also thanked the U.S. for sending stingers, and said they were used on Saturday.

"Just today we shot down three Russian attack aircrafts, which were bombing our cities with the use of stingers but we need -- so to say -- big air defense systems to ensure the safety of our skies. If we lose the skies, there will be much, much more blood on the ground,"Kuleba said.

In response to questions about NATO’s refusal to impose a no-fly zone over Ukraine, Kuleba said it’s a "sign of weakness," but stayed optimistic that they will change their minds.

"The time will come," he said.
