The U.S. will be providing Ukraine with $100 million in "civilian security" assistance, U.S. Secretary of State Antony Blinken announced Saturday, hours after he and Defense Secretary Lloyd Austin met with their Ukrainian counterparts.

The aid will provide equipment including armored vehicles, medical supplies, personal protective equipment and communications equipment, according to the Department of State.

The aid will go to Ukraine’s border guard, law enforcement and government infrastructure protection, Blinken said in a statement.

"With the U.S. government’s vital assistance, Ukrainian law enforcement officers are playing a key role in rescuing victims of the Russian government’s brutal assault, leading and protecting convoys of those displaced by attacks, and providing security to civilian areas torn apart by ruthless and devastating bombing," Blinken continued in the statement.

Two Russian missile strikes in Lviv hit an oil depot and a defense facility, Maksym Kozytskyi, Lviv's regional governor, confirmed in a press briefing Saturday.

Kozytskyi confirmed five people were injured at the site of the first strike and said firefighters are still putting out fires at the facility.

Lviv Mayor Andriy Sadovyi told reporters a school near the oil depot was damaged in the strike.

Both officials asked the media not to film the sites of the strikes.

President Joe Biden told the Ukrainian people, "We stand with you" in an address he gave at the Royal Castle in Warsaw, Poland, Saturday.

"We’ll not cease the efforts to get humanitarian relief wherever it is needed in Ukraine and for the people who’ve made it out of Ukraine. Notwithstanding the brutality of Vladimir Putin, let there be no doubt that this war [has] already been a strategic failure for Russia," Biden said.

"Putin thought Ukrainians would roll over and not fight, not much of a student of history," Biden said.

Biden also addressed the Russian people, telling them: "You, the Russian people, are not our enemy."

"The American people stand with you and the brave people of Ukraine for peace," Biden said.

In an address from Warsaw Saturday, President Joe Biden made remarks seemingly directed at Russian President Vladimir Putin and his invasion of Ukraine. "For god's sake, this man cannot remain in power," Biden said.

After the speech, the White House released a statement saying the president wasn't calling for a regime change.

“The President’s point was that Putin cannot be allowed to exercise power over his neighbors or the region. He was not discussing Putin’s power in Russia, or regime change,” a White House official said.

"These are not the actions of a great nation," Biden said, addressing the Russian people during his speech.

"Vladimir Putin's aggression have cut you, the Russian people, off from the rest of the world, and it’s taking Russia back to the 19th century. This is not who you are," Biden said.

Biden praised Ukrainian resistance, saying the U.S. stands with the people of Ukraine and will continue to support them.

"A dictator bent on rebuilding an empire will never erase a people's love for liberty. Brutality will never grind down their will to be free. Ukraine will never be a victory for Russia, for free people refuse to live in a world of hopelessness and darkness," Biden said.

All Russian troops have left the Ukrainian cities of Kyiv and Chernihiv, withdrawing north toward the borders of Belarus and Russia to consolidate before likely redeploying to the Donbas region in eastern Ukraine, a senior U.S. defense official told reporters Wednesday.

But even with the Russians gone, the territory remains treacherous.

"There are some indications that they left behind mines and things like that, so the Ukrainians are being somewhat careful in some areas north of Kyiv as they begin to clear the ground and clear the territory and re-occupy it," the official said.

While the U.S. hasn't yet seen these troops redeploy elsewhere in Ukraine, it'll likely happen soon, according to the official. Ukrainian forces are preparing for a major fight in Donbas, the official said.

The official also said the Pentagon is "monitoring" an apparent nitric acid explosion in Ukraine's Luhansk region, which Russia blamed on Ukraine.

"We've seen the Russians claim that this was a Ukrainian attack on this. We do not believe that is true," the official said. "We do believe that the Russians are responsible, but exactly what they used when they did it, why they did it, what the damage is, we just don't have that level of detail," the official said.

The official also noted that a small number of Ukrainians currently in the U.S. for "professional military education" were pulled aside for a couple days of training on Switchblade drones, which the U.S. is sending overseas as part of its military aid, according to the official.

"Although it's not a very difficult system to operate, we took advantage of having them in the country to give them some rudimentary training on that," the official said.
