The U.S. Department of Defense announced $400 million in new military aid for Ukraine, including eight folding armored bridges for the first time.

This is the Biden administration's 33rd drawdown of equipment from Department of Defense inventories for Ukraine.

Around 5,000 people still remain in the Ukrainian city of Bakhmut, including 37 children, according to Donetsk Oblast Regional Governor Pavlo Kyrylenko.

The losses in Bakhmut stand at the rate of one Ukrainian solider to seven Russian soldiers, Secretary of the National Security and Defense Council Oleksii Danilo said on TV.

Russian forces fighting for control of Bakhmut intensified shelling at access roads to the west, making it harder for Ukrainian forces to move in and out, Reuters reported Friday.

The State Department said Friday that Secretary of State Antony Blinken spoke with Ukrainian Foreign Minister Dmytro Kuleba about the brief conversation that took place at the G-20 summit between Blinken and Russian Foreign Minister Sergei Lavrov.

"The Secretary underscored to Foreign Minister Kuleba the United States’ enduring support for Ukraine as it defends itself against Russia’s brutal attacks, including the ongoing targeting of civilian infrastructure and resulting civilian casualties," State Department spokesman Ned Price said in a statement.

The U.S. will announce another assistance package for Ukraine on Friday, White House spokesperson John Kirby announced Thursday afternoon, but did not detail the exact size of this next round of support.

"You'll see us tomorrow, just unilaterally, the U.S. will have another round of assistance for Ukraine coming tomorrow. And it will include mostly ammunitions and munitions that the Ukrainians will need for the systems that they already have, like the HIMARS and the artillery."

The new aid comes as President Joe Biden meets with German Chancellor Olaf Scholz at the White House Friday to discuss ongoing support for Ukraine as Russia's invasion continues.

Kirby said the leaders would discuss the "kinds of capabilities that Ukraine continues to need in the weeks and months ahead."

He also said this will be a "true working visit" between Biden and Scholz and they are expected to discuss "recent engagements with Ukrainian officials, including the President's trip to Kyiv and meeting with President Zelenskyy, as well as Chancellor Schultz’s meeting with President Zelensky in Paris last month."

In the basement of the Syayvo bookstore in Ukraine's capital, hundreds of Russian language books stand piled, waiting to be pulped.

The books -- ranging from everything between the classics of Russian literature to works translated into Russian and Soviet-era textbooks -- have been donated by Ukrainians who have turned away from Russian culture to embrace their own since the invasion last year.

They are set to be recycled and turned into Ukrainian language texts or other products, with all profits going to support the war effort, Nadia Kibenko, the 32-year-old store worker who is handling the books, told ABC News. They have recycled 75 tons -- around 150,000 volumes -- since last July, she said. As a child, Kibenko grew up in a Ukrainian speaking household but, more often than not, only had the choice to read in Russian.

"We do not burn books," Kibenko told ABC News during a recent interview in Kyiv. "We just give them second life."

The cultural battleground is not just symbolic. Witnesses from the Russian occupied territories say that, in schools, Ukrainian language books were thrown out and replaced by Russian ones as new curricula taught Putin's view that Ukrainians and Russians are "one people."

A report published in December by PEN America, a New York-based literary and human rights organization, said that "culture was on the frontlines" and Putin "seeks not only to control Ukrainian territory, but to erase Ukrainian culture and identity."
