Zelenskyy says Putin is waging a 'gas war' against Europe; wheat prices rise after Odesa attack

This is CNBC's live blog tracking developments on the war in Ukraine.

A U.N.-backed deal to resume exports of Ukrainian grain has been thrown into doubt after missile strikes at the weekend.

The strikes, on the port city of Odesa, have been widely condemned, as the Kremlin insists that they hit military infrastructure.

Wheat prices have risen on news of the attack, after falling on Friday following the agreement between Russia and Ukraine.

The State Department said it is closely monitoring WNBA star Brittney Griner's trial in Russia as she heads back to court tomorrow.

"We are working around the clock behind the scenes quietly to do everything we possibly can to see to it that Brittany Griner's ordeal, just as Paul Whelan's ordeal, is put to an end just as soon as can be possibly managed," Price said, referencing a former U.S. Marine who is also detained in Russia.

Price added that senior embassy officials have been able to speak to Griner amid her trial in a Moscow court.

The 31-year-old Griner, who plays professional basketball in Russia during the WNBA offseason, was arrested in February at a Russian airport on accusations that she was smuggling hashish oil.

The president of a Ukrainian nuclear power plant company said Russian forces kidnapped about 100 of its employees.

"There are about 500 Russian soldiers on the territory of the plant. They are the ones letting employees into their working stations and control everything that is going on on the territory of the Zaporizhzhya nuclear power plant," Petro Kotin of Energoatom said, according to an NBC News translation.

Kotin added that Russian troops took ID badges and entered a secure area within the nuclear power plant. He said "what they did there is not known."

He said they may not have followed proper security controls and "it is quite possible that they got radioactive contamination on their clothes out of the control zone."

Ukrainian President Volodymyr Zelenskyy said that Russian President Vladimir Putin is waging a "gas war" against Europe.

"Russia is not going to resume gas supplies to European countries, as it is contractually obligated to do. And this is an open gas war, which Russia is waging against a united Europe," Zelenskyy said during a nightly address on the Telegram messaging app.

"They don't care what will happen to the people, how they will suffer from hunger due to the blocking of ports or from winter cold and poverty," Zelenskyy said, adding that Russia is engaging in "different forms of terror."

He also called on global leaders to sever trade ties with Russia "as much as possible" in order to pressure Moscow.

Russia's Gazprom further reduces gas flow of Nord Stream 1 pipeline, citing repairs

On Friday, Russian energy supplier Gazprom said it would not resume its supply of natural gas to Germany through the key Nord Stream 1 pipeline, blaming a malfunctioning turbine.

Russia's Gazprom said it would further reduce natural gas flows through a major pipeline to Europe to 20% of capacity, citing repairs of equipment.

The Russian state-owned company tweeted that it would reduce "the daily throughput" of the Nord Stream 1 pipeline to Germany to 33 million cubic meters as of Wednesday. The head of Germany's network regulator confirmed the reduction.

The move comes after Gazprom raised questions about the return of a part that has been at the center of tensions over natural gas deliveries through the pipeline, saying that it isn't satisfied with documents it has received.

The company reduced the gas flow through the Nord Stream 1 pipeline by 60% in mid-June, citing alleged technical problems involving the equipment that partner Siemens Energy sent to Canada for overhaul and couldn't be returned because of sanctions over Russia's invasion of Ukraine.

Germany has rejected Gazprom's technical explanation for the gas reduction, saying repeatedly that it was only a pretext for the Kremlin's political decision to sow uncertainty and further push up energy prices.

The United Nations has confirmed 5,237 civilian deaths and 7,035 injuries in Ukraine since Russia invaded its ex-Soviet neighbor on Feb. 24.

The Office of the U.N. High Commissioner for Human Rights said the death toll in Ukraine is likely higher, because the armed conflict can delay fatality reports.

The international organization 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.

Natalia Gavrilița, the prime minister of nearby Moldova spoke to CNN Sunday, saying "nobody is safe" with the conflict raging in Eastern Europe.

"It's a hypothetical scenario for now, but if the military actions move further into the southwestern part of Ukraine and toward Odesa then, of course, we are very worried," Gavrilița said.

"We are very worried, especially considering that troops are on the territory of the secessionist Transnistria region," she said.

"We are doing everything possible to maintain peace and stability and to ensure that the fighting does not escalate."

Moldova is home to a sizeable pro-Russian separatist population based in the breakaway state of Transnistria.

Russian Foreign Minister Sergey Lavrov insisted that the strikes in Odesa over the weekend targeted military infrastructure.

"There is nothing in the obligations that Russia took, including within the framework of the agreements signed on July 22 in Istanbul, which prohibit us from continuing the special military operation, destroying military infrastructure and other military targets," Lavrov said at a press conference alongside his Congolese counterpart Christophe Lutundula in Oyo, Congo.

The strike on Odesa, Ukraine's largest port, dealt another setback to so far fruitless efforts to mitigate a mounting global food crisis.

Kremlin spokesman Dmitry Peskov also told reporters separately that Russia's strikes wouldn't influence the gain exports from the region.

Ukrainian President Volodymyr Zelenskyy called the strikes on Saturday an act of barbarism.

Wheat futures prices for September on the Chicago Board of Trade were up 3.6% on Monday morning as traders showed caution on a grain export deal signed by Russia and Ukraine last week.

The two countries on Friday signed a U.N.-backed deal to resume exports of Ukrainian grain through the Black Sea. The deal is significant for global food supplies, but also as it's the first major agreement between the two sides since Moscow launched it's unprovoked onslaught on Feb. 24.

But Ukraine said Saturday that Russian missiles had hit the southern Ukrainian port of Odesa, throwing that new pact into doubt.
