Russia-Ukraine updates: US sanctions Russian military shipbuilder, diamond miner

President Joe Biden announced more aid to Ukraine Wednesday, saying that the "American people are answering [Ukrainian] President [Volodymyr] Zelenskyy's call for more help, more weapons for Ukraine to defend itself, more tools to fight Russian aggression."

Biden announced an additional $800 million in military assistance as part of the $13.6 billion aid package for Ukraine contained in the government spending bill Biden signed into law Tuesday, which includes weapons the Ukrainians have been requesting, such as anti-armor and anti-air systems.

“At the request of President Zelenskyy, we have identified and are helping Ukraine acquire additional longer range anti-aircraft systems and ammunitions for those systems," Biden said. "Our new assistance package also includes 9,000 anti-armor systems -- these are portable, high-accuracy systems, shoulder-mounted missiles, that the Ukrainian forces have been using."

The U.S. is also sending drones, "which demonstrates our commitment to sending our most cutting-edge systems to Ukraine for its defense," Biden said.

The new package will also supply Ukraine with machine guns, shotguns and grenade launchers.

"This could be a long and difficult battle," Biden said. "But the American people will be steadfast in our support of the people of Ukraine in the face of [Russian President [Vladimir] Putin’s immoral, unethical attacks on civilian populations. We are united in our abhorrence of Putin’s depraved onslaught, and we are going to continue to have their backs as they fight for freedom, their democracy, their very survival."

Biden did not directly address Zelenskyy's emotional appeal to lawmakers on Wednesday for the U.S. to back a no-fly zone, which the administration has repeatedly rejected.

By a vote of 13-2, the United Nations' highest court, the International Court of Justice, made a preliminary ruling that Russia "shall immediately suspend military operations."

The two votes against were from Russia and China.

Ukrainian President Volodymyr Zelenskyy reacted on Twitter, writing that “Russia must comply immediately." But the ruling is mostly symbolic as the ICJ has no direct means to enforce it.

White House national security adviser Jake Sullivan spoke with his Russian counterpart, Nikolay Patrushev, on Wednesday “to reiterate the United States’ firm and clear opposition to Russia’s unprovoked and unjustified invasion of Ukraine,” National Security Council spokesperson Emily Horne said in a statement.

She said Sullivan told Patrushev that Russia should stop attacking Ukraine if it's serious about diplomacy and warned “about the consequences and implications of any possible Russian decision to use chemical or biological weapons in Ukraine.”

Horne said Sullivan “clearly laid out” that the U.S. will continue “imposing costs on Russia” as well as support Ukraine and defend NATO’s eastern flank.

This conversation marked the first high-level engagement between the U.S. and Russia since the Kremlin launched its war against Ukraine.
