Russia-Ukraine updates: US to ban Russian carriers from its airspace

Ukraine’s president Volodymyr Zelenskyy said Saturday Western countries have agreed to disconnect Russia from the Society for Worldwide Interbank Financial Telecommunication (SWIFT) banking network.

"For Russia it will mean being cut off [from] normal financial civilization. This is a big diplomatic victory," he said. "Russia will suffer billions upon billions of financial losses -- their price for invasion."

Ukraine’s foreign minister said earlier that technical preparations have begun for disconnecting Russia from SWIFT and that the last holdouts, Germany and Hungary, have signaled they're no longer opposed.

Zelenskyy also said Turkey’s president has agreed to close the straits into the Black Sea to Russia.

Zelenskyy continued, "You know, it was a beautiful sunny day in Kyiv today that occupiers tried to ruin. But today is also the first day in the life of the baby girl born in the shelter in Kyiv metro station."

"We fight back strongly … and we will do our best to liberate our country," he said. "When babies come into this world even under shelling and fire, then the enemy has no chance in this war.”

President Joe Biden responded to former President Donald Trump's comments this week that Russian President Vladimir Putin’s actions in Ukraine are “genius."

"I put as much stock in Trump saying that Putin's a genius as I do when he called himself a stable genius," Biden said in a pre-recorded interview with Brian Tyler Cohen.

In a radio interview this week, Trump said it was "genius" that Putin declared a portion of Ukraine independent.

"Putin is now saying, 'It’s independent,' a large section of Ukraine. I said, 'How smart is that?' And he’s gonna go in and be a peacekeeper. That’s strongest peace force … We could use that on our southern border. That’s the strongest peace force I’ve ever seen," Trump said on the conservative talk radio program "The Clay Travis and Buck Sexton Show."

"Here’s a guy who’s very savvy," Trump said. "I know him very well. Very, very well."

Biden in the interview defended his sanctions on Russia as “nothing like” what the U.S. has done before and weighed what the other option could have been.

“You have two options: start a third World War, go to war with Russia physically. Or two, make sure that a country that acts so contrary to international law ends up paying the price," he said.

"There's no sanction that is immediate. It's not like you can sanction someone and say, 'You no longer are going to be able to be president of Russia,'" he continued. "But I think the sanctions -- I know -- I know the sanctions are the broadest sanctions in history."

“Russia will pay a serious price for this short term and long term, particularly long term," Biden said.

Biden held a secure call with his national security team Saturday morning on the latest developments, according to a White House official.

The new package of $350 million in assistance to Ukraine will include “anti-armor, small arms and various munitions, body armor, and related equipment in support of Ukraine’s front-line defenders facing down Russia’s unprovoked attack," Pentagon spokesman John Kirby said.

It also includes portable surface-to-air missiles (MANPADS) in the Pentagon's inventory, a U.S. official told ABC News.

It's not clear how the equipment will be provided to the Ukrainian military. The U.S. official said they can't speak to logistics or timing, but said, "Time is clearly of the essence, so we expect deliveries to start very soon."

This brings total U.S. security assistance approved for Ukraine in the last year to $1 billion.
