Hillary Clinton said in an interview on MSNBC's "Morning Joe" on Friday that she believes the Biden administration and U.S. allies need to impose harsher sanctions on Russia that target President Vladimir Putin himself and his oligarchs.

The former secretary of state said she hopes the U.S. and its European allies "move even more quickly" to impose sanctions not only on the Russian economy, but also on individual actors "all the way up to Putin." 

"I think that the only pressure that Putin would respond to, or that could have any kind of impact on his thinking, would be [sanctioning] those who he relies on to launder his money, to keep the funding going into his secret accounts," she said. "We've got to go after those oligarchs who are supporting Putin financially."

Clinton said the U.S. needs to call the oligarchs out by name and go after their assets, such as by a temporary suspension of access to things such as their yachts or huge houses or their bank accounts. 

"Because if we don't up the pressure now, whatever we are doing, which I think is absolutely right to bring the world together to bring more troops to protect our NATO allies, it will take longer and Ukraine will be burning," she warned. 

She said there is an "urgency" to imposing these more powerful sanctions because some of the attacks haven't gone as well as Russia had wanted in Ukraine. As a result, she said, "They will get more vicious and they will attack even more randomly and indiscriminately.”

The United Nations' human rights office says it has received reports of at least 25 people killed and more than 100 injured in Ukraine due to "shelling and air strikes." 

The Office of the United Nations High Commissioner for Human Rights said in a statement Friday that the U.N. Human Rights Monitoring Mission in Ukraine had received reports of at least 102 people injured, in addition to the 25 killed, as of midnight Thursday going into Friday.

"This is more than the total number of civilian casualties recorded by the U.N. Human Rights Office on both sides of the contact line for the whole of 2021," it said, noting that the figures for 2021 were 25 killed and 85 injured.

Of those civilians killed or wounded, the U.N. human rights office said 23 were killed and 91 injured in government-controlled territory, including in the Donetsk, Cherkasy, Chernihiv, Kharkiv, Kherson and Luhansk regions. 

"Because of the security situation, civilian casualties in Government-controlled territory are likely to be under-reported, and real figures, therefore, could be higher," the office said. 

In armed group-controlled territory, it said, two people were killed and 11 injured in Donetsk and Horlivka on Thursday.

"Our colleagues on the ground are working to corroborate these figures. However, as indicated, the figures we have are likely to be under-estimates," it said, adding that it is "currently difficult to verify information, given both the security situation as well as the number of false reports emerging amid an information war."

Iryna Venediktova, prosecutor general of Ukraine, said Friday that an orphanage in the village of Vorzel outside Kyiv was hit by shrapnel from a Russian missile.

"As a result of these illegal actions, there are no victims, as at the time of the hit the children and staff of the orphanage were in other premises," Venediktova wrote on Facebook.

NBC News has not confirmed the damage to the orphanage, which Venediktova said houses 50 children.

Dmytro Kuleba, Ukraine's minister of foreign affairs, said on Twitter that the situation constituted a war crime.

"Together with the General Prosecutor’s Office we are collecting this and other facts, which we will immediately send to the Hague," he wrote.

Formula One’s governing body has stripped Russia of the right to host a Grand Prix. 

"We are watching developments in Ukraine with sadness and shock and hope for a swift and peaceful resolution to the current crisis,” the sport's governing body, the FIA, said in a statement Friday. The Russian Grand Prix last took place in September 2021 and was due to take place again in September this year.

"The FIA Formula 1 World Championship visits countries all over the world with a positive vision to unite people, bringing nations together," it added. 

Four-time F1 champion Sebastian Vettel said Thursday he would not race in Russia, and current champion Max Verstappen agreed with him but stopped short of saying he would skip the event.

It comes after European soccer’s governing body, UEFA, pulled the Champions League final from Russia replacing St. Petersburg with Paris. 

German soccer club Schalke also said Thursday that it would remove its sponsor, Russian gas company Gazprom, from its shirts.

Russia is ready to conduct high-level negotiations with Ukraine, Putin told Chinese President Xi Jinping in a phone call Friday.

According to a summary of the call from China's Foreign Ministry, Putin discussed his view of the historical background of the Ukraine situation, as well as Russia's position on its special military operation in eastern Ukraine.

He told Xi that the U.S. and NATO, the U.S.-led military alliance that Ukraine has expressed interest in joining, had ignored Russia's "legitimate security concerns" for a long time. They repeatedly reneged on their commitments and instead expanded their military deployment to the east, he said, challenging Russia's "strategic bottom line." 

Xi told Putin that China supports Russia and Ukraine in solving the issue through negotiation, and he repeated China's position that "Cold War thinking" should be abandoned and that the legitimate security concerns of all parties should be valued and respected. 

Pope Francis visited the Russian Embassy in Rome on Friday in an extraordinary gesture to convey his personal concerns about the conflict in Ukraine. 

The Vatican confirmed to NBC News that the pope had made the visit, which appears to have no recent precedent. 

Typically, popes receive ambassadors and heads of state in the Vatican, with the Vatican foreign minister expected to summon the ambassador under expected diplomatic protocol.

In this case, however, Francis took it upon himself to make the visit in a move appearing to reflect how upset he is at the situation unfolding in Ukraine.

Russian Ambassador to the Vatican Alexander Avdeev told Russia's state-run Tass news agency Friday that Francis "wanted to personally ask about the situation in Donbass and Ukraine."

The pope made the visit after the Vatican had announced that he had canceled a scheduled visit to Florence for Sunday and would not preside over Ash Wednesday commemorations next week due to "acute" knee pain.

The Vatican said Francis' doctors had prescribed a period of rest, with the pope having long suffered from sciatica nerve pain.

Ukrainians are queuing up in large numbers across the country to donate blood after President Volodymyr Zelenskyy appealed on Thursday for the “wounded soldiers in hospital who need blood.”

Almost 500 people donated blood in the capital city of Kyiv alone, three times the average, the administration of Kyiv said on its Telegram channel. The city will also operate blood centers 24 hours a day.

Anyone over the age of 18 can donate blood as long as there are no medical complications.
