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.

The United Kingdom announced a new wave of sanctions on Thursday targeting Russians involved in the barbaric treatment of children in Ukraine.

Maria Lvova-Belova, Russia's Children Rights Commissioner, tops the new list of sanctioned individuals for her alleged involvement in the forced transfer and adoption of Ukrainian children. She has been accused of enabling 2,000 vulnerable children being violently taken from the Luhansk and Donetsk regions and orchestrating a new policy to facilitate their forced adoptions in Russia.

“Today we are targeting the enablers and perpetrators of [Russian President Vladimir] Putin’s war who have brought untold suffering to Ukraine, including the forced transfer and adoption of children,” U.K. Foreign Secretary Liz Truss said in a press release.

More than 900 children were injured in Ukraine as a result of the full-scale armed aggression by the Russian Federation, according to the Ukrainian Prosecutor General’s latest report. Over 320 children were killed and more than 580 were injured.

These figures are far from being final, with more information slowly trickling in from places of active hostilities, as well as the temporarily occupied and liberated territories.

The UK's sanction list also includes Patriarch Kirill, the head of the Russian Orthodox Church, for his support and endorsement of Putin’s war.

Several members of Putin's political elite, along with four Military Colonels from a unit known to have killed, raped and tortured civilians in the Ukrainian town of Bucha, appear on the list too.

“Putin’s allies continue to choose to turn a blind eye to alleged war crimes and support his bloody offensive,” the U.K. government said. With Putin’s aggression reaching beyond Ukraine as Russian exports fuel conflict across the globe, the official press release read, the new sanctions also hit Myanmar’s military Junta.

The Junta relies heavily on Russian air assets and limiting it will cut Putin off from profiting from sales that fund his war machine, the U.K. said.
