UN says 2,729 killed in Ukraine since start of war, warns death toll is likely higher

The United Nations says it has confirmed 2,729 civilian deaths and 3,111 injuries in Ukraine since Russia invaded its ex-Soviet neighbor on Feb. 24.

Of those killed, the U.N. has identified at least 61 girls and 73 boys, as well as 67 children whose gender is unknown.

The Office of the UN High Commissioner for Human Rights said Monday that the death toll in Ukraine is likely higher, citing delayed reports due to the armed conflict.

The international body said most of the civilian casualties recorded were caused by the use of explosive weapons with a wide impact area, including shelling from heavy artillery and multiple launch rocket systems, as well as missiles and airstrikes.

Sixth round of EU sanctions on Russia coming ‘very soon,’ energy commissioner says

A sixth round of EU sanctions is set to be imposed on Russia “very soon,” the bloc’s energy commissioner Kadri Simson told press in Warsaw.

Simson said that the date the sanctions will be enacted has not yet been decided, as any measures would need to be approved by all 27 EU member states. Simson did not specify exactly what the sanctions would target, though the EU has come under pressure for its continued buying of Russian energy resources, providing Moscow with billions in revenues every week.

The bloc has not moved to sanction Russian oil or gas, in large part due to already high fuel prices and staunch opposition to the move by countries that rely heavily on imports of those commodities from Russia, including Germany, Hungary and Austria.

He is due to meet Russian President Vladimir Putin later today.

UN secretary general travels to Moscow to meet with Putin amid criticism from Ukraine

United Nations Secretary General Antonio Guterres has traveled to Moscow to meet Russian President Vladimir Putin. The visit is aimed at gaining ground for cease-fires to help fleeing civilians, and trying to involve the U.N. more deeply in brokering mediation efforts between Russia and Ukraine.

It comes after more than 200 former U.N. officials wrote Guterres a letter last week calling on him step in and take a firmer role in conflict resolution, “out of concern for the existential challenge that the United Nations is facing in this historic juncture.”

Ukrainian officials have criticized Guterres for visiting Moscow before visiting Kyiv. The U.N. chief is also expected to meet with Russian Foreign Minister Sergey Lavrov before traveling to Ukraine.

“It is simply wrong to go first to Russia,” Ukrainian President Volodymr Zelenskyy told press on Saturday. “There is no justice and no logic in this order. The war is in Ukraine, there are no bodies in the streets of Moscow. It would be logical to go first to Ukraine, to see the people there, the consequences of the occupation.”

Ukrainian attacks on Russian soil are ‘completely legitimate,’ UK minister says

Ukraine is justified in carrying out attacks on Russian territory, one U.K. minister has said, following accusations from Moscow in recent days that Ukrainian operators had fired on Russian facilities, including an oil depot near the countries’ shared border.

It is “completely legitimate for Ukraine to be targeting in Russia’s depth in order to disrupt the logistics that if they weren’t disrupted would directly contribute to death and carnage on Ukrainian soil,” U.K. Armed Forces Minister James Heappey told Times Radio.

Russia’s invasion of Ukraine set off the war, “and in war Ukraine needs to strike into its opponents depth to attack its logistics lines, its fuel supplies, its ammunition depots, and that’s part of it,” he said.

Large fires ripped through oil depots in Russia’s western city of Bryansk on Monday, less than 100 miles from the Ukrainian border. The facility is a major logistical center for Russia’s war operations.

Heappey also appeared to emphasize that the West was not responsible for these attacks, despite providing Ukraine with weapons that have the range to reach Russian territory. He pointed out that many countries use arms imported from other countries, saying, “You tend not to blame the country that has manufactured it, but the country that has fired it.”

U.K. dismisses Lavrov’s ‘bravado,’ says there’s no imminent threat of nuclear war

Britain’s armed forces minister has played down Russian Foreign Minister Sergey Lavrov’s warning that the war with Ukraine could escalate into a nuclear one.

Lavrov said late on Monday that the risks of nuclear war are now “very, very significant and should not be underestimated” but the remarks were dismissed as “bravado” by U.K. minister James Heappey.

“Lavrov’s trademark over the course of 15 years or so that he has been the Russian foreign secretary has been that sort of bravado. I don’t think that right now there is an imminent threat of escalation,” James Heappey told the BBC Breakfast program on Tuesday.

When asked about whether Russia would use a tactical nuclear weapon, Heappey said he thinks there’s a “vanishingly small” possibility of that sort of escalation.

Russia and India were reportedly in talks to restart coking coal trade

Officials from Russia and India met last week in hopes of resolving coking coal supply issues, Reuters reported citing sources.

Russian coking coal exports to Indian steelmakers have stalled since March due to payment methods, a trade source and an Indian government source said, according to Reuters. That’s despite New Delhi signing a plan last year to import coking coal from Russia.

Coking coal is essential in the production of steel, and Russia typically supplies about 30% of the coking needs of the European Union, Japan and South Korea.

Russian trade officials are reportedly concerned about the sanctions from the West and requested that India continue with the deal, the sources said.

Indian officials were invited to visit Russia to strategize how to secure smooth shipments of coking coal, sources said, according to Reuters.

“The risks are really very, very significant,” Lavrov told Channel One. However, he also added that there was a danger the risks were being “artificially” inflated.

UK says Ukraine’s grain harvest is likely to be about 20% lower than in 2021

Russia’s invasion has “significantly” disrupted Ukrainian agricultural production, the British defense ministry said in an intelligence update.

“The Ukrainian grain harvest for 2022 is likely to be around 20 per cent lower than 2021 due to reduced sowing areas following the invasion,” the U.K. ministry said.

Reduced grain supply from Ukraine — the world’s fourth largest producer and exporter of agricultural goods — would not only cause inflationary pressures and elevate the global price of grain, but also impact global food markets, the ministry said.

Grain prices have surged since the invasion began, and Morgan Stanley expects grain prices to remain above last year’s levels till 2023.

“High grain prices could have significant implications for global food markets and threaten global food security, particularly in some of the least economically developed countries,” the British ministry said.

‘We want to see Russia weakened,’ U.S. Defense Secretary Austin says

Washington wants to see Russia “weakened” as part of its aims in arming and supporting Ukraine, Defense Secretary Lloyd Austin said Monday during a visit to Kyiv, the first such high-level visit from a U.S. official since the war began.

“We want to see Ukraine remain a sovereign country, a democratic country able to defend its sovereign territory. We want to see Russia weakened to the degree that it cannot do the kinds of things it has done in invading Ukraine,” Austin told the press.

“It has already lost a lot of military capability, and a lot of its troops, quite frankly. In terms of our — their ability to win, the first step in winning is believing that you can win. And so, they believe that they can win, we believe that they can win, if they have the right equipment.”

The visit saw the U.S. pledge more military and diplomatic support to Ukraine as the Russian invasion entered its 60th day.

Mariupol officials say new mass grave found

Officials in the embattled Ukrainian city of Mariupol say a new mass grave has been identified north of the city.

Mayor Vadym Boychenko said authorities are trying to estimate the number of victims in the grave about 10 kilometers (about 6 miles) north of Mariupol.

Satellite photos released over the past several days have shown what appear to be images of other mass graves.

Mariupol has been decimated by fierce fighting over the past two months. The capture of the city would deprive Ukraine of a vital port and allow Moscow to establish a land corridor to the Crimean Peninsula, which it seized from Ukraine in 2014.
