Ukraine's defense ministry said it found 132 "tormented bodies" of tortured, murdered citizens in the town of Makariv, after Russian forces retreated.

The ministry said it uncovered "new monstrous war crimes," saying the town is "half ruined."

The Russian defense ministry claimed it fired on the Ukrainian Apache, a dry-cargo ship, which allegedly changed course and attempted to break through to the Mariupol seaport, the ministry said.

The Ukrainian dry-cargo ship did not respond to Russian border guards' demands to contact them through the international channel and continued heading in the direction of Mariupol port, Russia claimed.

Russia said two border patrol ships fired warning artillery along the vessel's course, but the cargo ship did not change course or slow down.

The cargo ship, over radio communication, transmitted a message, saying, "I am 'Maniac', coming for you," and signal fires were observed on the shore, according to Russia's defense ministry.

The Black Sea Fleet then opened artillery fire on the Apache dry-cargo ship to block the vessel, Russia's defense ministry said.

A direct hit caused a fire in the stern of the ship and it then went adrift. The crew got in touch with border ships with a request to cease fire and said they will comply with the demands of Russian sailors, Russia said.

Russia said no crew members were injured and the fire was extinguished by the ship's crew.

The ship was inspected and then convoyed to the Yeysk port along with its crew, according to Russia.

British Prime Minister Boris Johnson met with Ukrainian President Volodymyr Zelenskyy in Kyiv on Saturday, according to the Ukrainian Embassy in London.

"The Prime Minister of the United Kingdom Boris Johnson is one of the most principled opponents of the Russian invasion, a leader in sanctions pressure on Russia and defence support for Ukraine. Congratulations in Kyiv, my friend!" Zelenskyy said in a post online.

Britain announced it will send 120 armored vehicles and new anti-ship missile systems to support Ukraine, according to the The Associated Press.

"Today I met my friend President @ZelenskyyUa in Kyiv as a show of our unwavering support for the people of Ukraine. We're setting out a new package of financial & military aid which is a testament of our commitment to his country's struggle against Russia’s barbaric campaign," Johnson said.

Ukraine claimed Saturday that its intelligence indicates Russian forces are currently regrouping in eastern Ukraine, then the tankers intend to move toward Kharkiv, Ukraine's Defense Intelligence Chief Kyrylo Budanov said.

Russians are also regrouping in the direction of Izum, in the Kharkiv region, the Ukrainians said.

"They plan to enter Kharkiv in the first place. They will try to conquer the city of Mariupol and only after that they can try to initiate Kiev," Budanov said in an interview on CNN.

To compensate for their significant losses in Ukraine, the Russian army is transferring additional troops to Belgorod (Russia), from where they are relocated to Kharkiv region, the Ukrainians claimed.

Budanov said Ukraine needs serious military support from allies so its soldiers can more effectively resist Russian aggression.

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."
