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.

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.
