Oil jumps over 3% as deaths near Kyiv prompt talk of new sanctions
Oil prices jumped over 3% with investors worried about tighter supply as mounting civilian deaths in Ukraine increased pressure on European countries to impose sanctions on Russia's energy sector.
Global benchmark Brent crude jumped $3.14, or 3%, to settle at $107.53 a barrel. U.S. West Texas Intermediate crude rose $4.01, or 4%, to settle at $103.28 a barrel. Trading was volatile with both contracts rising after being down more than $1.
German Chancellor Olaf Scholz said Russian President Vladimir Putin and his supporters would "feel the consequences" of events in Bucha, outside the capital Kyiv, where a mass grave and tied bodies shot at close range were found.
Western allies would agree on further sanctions against Moscow in coming days, he said, though the timing and reach of the new package was not clear. France's President Emmanuel Macron suggested sanctions on oil and coal, adding there were very "clear clues pointing to war crimes" by Russian forces.

Evidence of war crimes mount in Bucha amid Russian retreat
Editor's Note: Graphic content. The following post contains images of dead bodies found in the suburban Kyiv town of Bucha.
The Kremlin faced renewed global outrage and accusations of war crimes on the heels of a grisly discovery of civilians tortured and shot at close range in the streets of Bucha, Ukraine.
Over the weekend, Ukrainian President Volodymyr Zelenskyy traveled from Kyiv to the nearby town of Bucha to see the aftermath of a Russian troop pullout which he later described as a "genocide." Bodies of civilians lay scattered across the streets, some with their hands tied and gunshot wounds to the back of the head.
U.S. National security advisor Jake Sullivan called the images from Bucha "tragic" and "shocking."
"Unfortunately, they're not surprising. We released information even before Russia's invasion showing that Russia would engage in acts of brutality against civilians," Sullivan told reporters at the White House. Biden's top security advisor said the U.S. was working on additional sanctions measures alongside European allies.
Earlier on Monday, President Joe Biden called Russian leader Vladimir Putin a "war criminal" who should be put on trial for ordering violence in Ukraine.
"This guy is brutal, and what's happening in Bucha is outrageous and everyone's seen it," Biden told reporters gathered at Fort McNair, adding, "I think it is a war crime ... He should be held accountable."
Since the Kremlin's Feb. 24 invasion of Ukraine, the United Nations has confirmed 1,430 civilian deaths and 2,097 injuries. The war has also displaced more than 4.2 million Ukrainians, mostly the elderly, women and children.

White House warns of renewed Russian fight in Ukraine after weeks of slow gains
National security advisor Jake Sullivan warned that Russian forces are currently gearing up for a more aggressive fight in Ukraine after nearly six weeks of war.
"At this juncture, we believe that Russia is revising its war aims. Russia is repositioning its forces to concentrate its offensive operations in eastern and parts of southern Ukraine, rather than target most of the territory," Sullivan told reporters, citing failed Russian attempts to capture Kyiv.
"All indications are that Russia will seek to surround and overwhelm Ukrainian forces in eastern Ukraine. We anticipate that Russian commanders are now executing the redeployment from northern Ukraine to the region around the Donbas," Sullivan added.
He added that Russia's renewed ground offensive in eastern Ukraine will likely also "include air and missile strikes across the rest of the country to cause military and economic damage, and frankly, to cause terror."

France and Germany expel additional Russians from diplomatic missions
France and Germany said they were expelling several Russian personnel serving under the cover of diplomatic status, citing security concerns.
"France decided this evening to expel many Russian personnel with diplomatic status assigned to France whose activities are contrary to our security interests," the French Foreign Ministry said in a statement.
"This action is part of a European approach. Our first responsibility is always to ensure the safety of French and Europeans," the statement added.
Berlin also barred several Russian personnel from continuing their work within Germany.
"Their work is a threat to those who seek shelter with us. We will no longer tolerate this," German Foreign Minister Annalena Baerbock said in a statement.
Last week, in a coordinated move, Ireland, Belgium, the Netherlands and the Czech Republic expelled a total of 43 Russian diplomats suspected of spying. The action followed similar steps taken by Poland.

Russian oligarch Vekselberg accused of fraud, money laundering as his yacht is seized
U.S. officials accused Russian oligarch Viktor Vekselberg of bank fraud and money laundering as his yacht was seized in Spain.
The seizure of the $90 million mega yacht followed a move by the U.S. and its allies to sanction Vekselberg in response to Russia's invasion of Ukraine.
An FBI search warrant alleged Vekselberg conspired to commit bank fraud and money laundering to obscure his ownership of the yacht.
A spokesperson for Vekselberg did not respond to a request to comment.

UK calls for more sanctions: 'Money is still flowing from the West into Putin's war machine'
UK Foreign Secretary Liz Truss called for tougher sanctions against Russia during a joint press conference with Ukrainian Foreign Minister Dmytro Kuleba in Warsaw.
Since Russia's Feb. 24 invasion of Ukraine, the UK has delivered its strongest sanctions ever levied on a country.
"The reality is that money is still flowing from the West into Putin's war machine and that has to stop," Truss said, adding that she would raise this issue with G-7 and NATO allies this week.
Truss also joined the U.S. in calling for Russia's suspension from the United Nations Human Rights Council. Her demand came on the heels of alarming reports of attacks on civilians in the Ukrainian town of Bucha outside Kyiv.
"After these appalling crimes, Russia has no place on the Human Rights Council," she said, adding that the UK is currently gathering evidence of war crimes in Ukraine.

U.S. military cannot independently confirm war crimes in Bucha, Defense official says
Editor's Note: Graphic content. The following post contains a photo of dead bodies found in the suburban Kyiv town of Bucha.
The U.S. military could not independently confirm reports of mounting evidence of Russian war crimes in Ukraine.
A senior U.S. Defense official, who spoke on the condition of anonymity to share details of the Pentagon's thinking, described the reports of atrocities in Bucha, a town in the suburbs of Kyiv, as "clearly deeply troubling."
The official, who was aware of the accounts out of Bucha, described the imagery as "disgusting" and "sickening." The official added that the U.S. had no evidence that Russian troops were given specific orders to kill civilians in Bucha.
Earlier on Monday, President Joe Biden called Russian leader Vladimir Putin a "war criminal" who should be put on trial for ordering violence in Ukraine.
"This guy is brutal, and what's happening in Bucha is outrageous and everyone's seen it," Biden told reporters gathered at Fort McNair, adding, "I think it is a war crime ... He should be held accountable."

About 65% Russian forces have left Kyiv, U.S. Defense official says
About 65% of the Russian forces once near Kyiv have now re-positioned closer to Belarus, according to a senior U.S. Defense official.
The U.S. believes these Russian troops are being resupplied with additional manpower in Belarus before deploying back to the fight in Ukraine. When asked where the troops would likely go, the official said that the Pentagon believes the majority of them will move to the Donbas region but has not seen such a deployment.
The Defense official says that the U.S. believes that the "vast majority" of Russian forces are still in Ukraine and that Kyiv is still under threat.

Biden also said he plans to slap additional sanctions on Russia for its unprovoked attack on Ukraine.

JPMorgan CEO Dimon says Ukraine war, inflation, Covid may ‘dramatically increase risks ahead’
Jamie Dimon, CEO and chairman of the biggest U.S. bank by assets, pointed to a potentially unprecedented combination of risks facing the country in his annual shareholder letter.
Three forces are likely to shape the world over the next several decades: a U.S. economy rebounding from the Covid pandemic; high inflation that will usher in an era of rising rates, and Russia's invasion of Ukraine and the resulting humanitarian crisis now underway, according to Dimon, CEO of JPMorgan.
"Each of these three factors mentioned above is unique in its own right: The dramatic stimulus-fueled recovery from the COVID-19 pandemic, the likely need for rapidly raising rates and the required reversal of QE, and the war in Ukraine and the sanctions on Russia," Dimon wrote.
"They present completely different circumstances than what we've experienced in the past – and their confluence may dramatically increase the risks ahead," he wrote. "While it is possible, and hopeful, that all of these events will have peaceful resolutions, we should prepare for the potential negative outcomes."

Bucha killings to prompt further sanctions; EU to discuss import ban on Russian gas
European leaders have called for a wave of tougher economic sanctions against Russia in light of the devastation in the Ukrainian town of Bucha.
German Defense Minister Christian Lindner has said the European Union must discuss banning the import of Russian gas deliveries.
That appears to mark a major policy shift for Europe's largest economy, and comes as pressure intensifies on policymakers to further isolate the Kremlin on the global stage.
Berlin has so far resisted calls to impose an embargo on Russian energy exports, citing the region's dependence on Russian gas. Russia supplies around 40% of Europe's gas supplies.
Separately, Italy's Foreign Minister Luigi Di Maio told the country's Rai 3 channel that events in Bucha would trigger a new wave of sanctions, Reuters reported, before adding that there could soon be a debate on whether to impose an import ban on Russian fossil fuels.

"All those involved in these war crimes must bear responsibility," the ministry said on Twitter.
Separately, President Salome Zourabichvili said the "massacre" in Bucha was a "crime against humanity."
Russia has recognized the breakaway regions of South Ossetia and Abkhazia as independent after fighting a war with Georgia in 2008.
The country, which borders Russia and sits at the intersection of Europe and Asia, has repeatedly voiced support for the people of Ukraine but refused to join economic sanctions designed to isolate the Kremlin.

"We will unmask Ukrainian provocateurs and their Western patrons."
Polyanskiy did not elaborate on how Ukrainians were being provocative in Bucha, a city which Russian troops invaded as part of their failed drive toward Kyiv.
