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 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."

The U.S. estimates that Russia has suffered over 100,000 casualties, including over 20,000 killed in action, since it stepped up its winter offensive in December, a White House National Security Council told ABC News.

Half of the 20,000 killed in action were members of the Russian-backed private military Wagner Group, according to White House spokesman John Kirby. The majority of Wagner fighters killed were allegedly ex-convicts, according to Kirby.

Kirby said that the data came from "some downgraded intelligence" that the U.S. has been able to collect. He was unable to provide data on deaths of Ukrainian fighters.

Kirby had earlier told reporters that the Russian casualties took place from battles in Bakhmut since December, however, the National Security Council member said the data encompasses all winter battles.

Many, but not all, of these Russians were injured or killed in the Bakhmut fighting, according to the official.

Kirby emphasized that the U.S. thinks Bakhmut holds "very little strategic value for Russia" and if captured by Russia, it "would absolutely not alter the course of the war in Russia’s favor."
