Italy's Ministry of Economy and Finance on Saturday impounded the Scheherazade, a yacht said to be worth $700 million, which allegedly belonged to Russian President Vladimir Putin.

The superyacht has been under investigation for months for possible connections to Putin and other Russians sanctioned by the EU. The Scheherazade was being refurbished in the Tuscan port of Marina di Cararra.

The investigation conducted by Italian authorities found significant economic and business connections between the owner of the Scheherazade and prominent people in the Russian government and other Russians sanctioned by the EU.

Italian officials also recommended to the EU Council that the owner of the boat be added to the list of Russians sanctioned for the war in Ukraine.

The war in Ukraine is taking a toll on Russia's military, the U.K. Ministry of Defense said Saturday.

"The conflict in Ukraine is taking a heavy toll on some of Russia’s most capable units and most advanced capabilities. It will take considerable time and expense for Russia to reconstitute its armed forces following this conflict," the ministry said in a statement.

Adding, "It will be particularly challenging to replace modernized and advanced equipment due to sanctions restricting Russia’s access to critical microelectronic components."

At least one T-90M, Russia's newest tank, with its strongest armor, has been destroyed in the fighting, the Ministry of Defense said.

The Russian military has approximately 100 T-90M tanks currently in service, including those in Ukraine, but the system's upgraded armor "remains vulnerable if unsupported by other elements," the defense ministry said.

First Lady Jill Biden kicked off the first day of her overseas trip by visiting Mihail Kogalniceanu Air Base in Romania, where she met with U.S. troops and NATO military leadership.

The U.S. deployed troops to the base, which is about 60 miles from the border with Ukraine, in the leadup to Russia's invasion of Ukraine.

Prior to departing the U.S. last night, the first lady told reporters, "It was so important to the president and to me that the Ukrainian people know that we stand with them."

Biden drew cheers Friday when she greeted soldiers with a bottle of ketchup in hand -- a commodity that has been in short supply on the base, according to her spokesperson.

Wearing a Beau Biden Foundation hat, the first lady helped serve mac and cheese and potatoes and shook hands and took photos with the service members. She also participated in a special story-time with United Through Reading, an organization that connects military families with a deployed service member through video recordings and virtual book readings.

Biden also met with members of the Delaware National Guard before departing the base for Bucharest.

The U.S. has announced another package of security assistance that will provide "additional artillery munitions, radars, and other equipment to Ukraine," according to a Friday afternoon statement from President Joe Biden.

The U.S. will provide up to $150 million in new security assistance for Ukraine, according to a memorandum from Biden.

"With today’s announcement, my Administration has nearly exhausted funding that can be used to send security assistance through drawdown authorities for Ukraine," Biden said in the statement. "For Ukraine to succeed in this next phase of war its international partners, including the U.S., must continue to demonstrate our unity and our resolve to keep the weapons and ammunition flowing to Ukraine, without interruption. Congress should quickly provide the requested funding to strengthen Ukraine on the battlefield and at the negotiating table."

The package includes 25,000 155mm artillery rounds, counter-artillery radars, electronic jamming equipment, field equipment and spare parts, according to Pentagon spokesperson John Kirby.

"Capabilities in this package are tailored to meet critical Ukrainian needs for today's fight as Russian forces continue their offensive in eastern Ukraine," Kirby said in a statement.

This marks the ninth drawdown of equipment from Department of Defense inventories for Ukraine since August 2021, according to Kirby.

White House national security advisor Jake Sullivan hinted Thursday of more sanctions coming against Russia in the "next week or two" aimed at targeting ways Moscow is evading sanctions already imposed.

“Where our focus will be over the course of the coming days is on evasion,” Sullivan said Thursday at the Economic Club of Washington. “As Russia tries to adjust to the fact that it’s under this massive economic pressure, what steps do they take to try to evade our sanctions and how do we crack down on that? And I think we'll have some announcements in the next week or two that identify targets that are trying to facilitate that evasion both inside Russia and beyond."

When Sullivan was asked whether sanctions will automatically be lifted if a negotiated peace deal between Russia and Ukraine is worked out, he appeared cautious with his words, saying, “a lot of that depends on what the shape and scope” of the agreement is.

“A lot of it depends on what the Ukrainians, in consultation with us and the Europeans come to agree to," Sullivan said. "You know, we're not going to do a deal over the head of the Ukrainians where we give a bunch of sanctions relief to Russia. But if some measure of sanctions relief were built in to some credible diplomatic solution led by the Ukrainians, that's something that we would happily discuss."

But Sullivan said Russian oligarchs shouldn't expect to ever get back their yachts and other assets seized under sanctions that have been imposed, saying the ultimate goal is "not to give them back” once the war is over.

“The president is actively looking at how we can deal with the fact that as we seize these assets, our goal is not to give them back. Our goal is to put them to a better use than that," Sullivan said. "But I'll be careful in what I say today because there's an ongoing kind of policy process around how we end up dealing with that question. But, rest assured, that the goal is not just to sit on them for a while."
