Russia-Ukraine updates: Putin suspends key US-Russia nuclear treaty in speech denouncing West

As Ukrainian forces advance to capture the city of Kherson, Russian forces are ordering civilians out of parts of the now-occupied city. Some 70,000 people along a 15 kilometer (10 mile) stretch of the left bank of the Dnipro River will be evacuated deeper into the Kherson region or to Russia, according to the Russian-installed leader of the occupied Kherson region, Vladimir Saldo.

Russia had previously ordered civilians out of an area it controls on the west bank of the river.

State Department spokesperson Ned Price on Monday lambasted Russia's recent decision to withdraw from the U.N.-brokered deal that allowed for grain to be exported through the Black Sea -- likely to be a chief focus of this week’s G-7 ministerial meeting and potentially the G-20 Leaders' Summit next month.

"We deeply regret Russia's decision to suspend its participation in the Black Sea Grain Initiative, which is having immediate, harmful impacts on global food security," Price said during a press briefing. "Russia should return to full participation in the initiative, and we urge all parties to swiftly agree to sustain this crucial program through the months to come."

"Any disruption to the initiative risks spiking food prices, lowering the confidence of insurers and commercial shippers who have returned to Black Sea routes, and further imposing hardships on low-income countries already reeling from dire humanitarian crises and global food insecurity," he added.

Price said Russia's reneging had already caused future contracts for foodstuff to rise, even though some ships appear to have been allowed to pass through the water routes with their cargo following Moscow's announcement.

"We've seen Russia engage in what appears to be collective punishment for the people of Ukraine," he said. "But Moscow's suspension of the initiative would be tantamount to collective punishment for the rest of the world -- but especially lower- and middle-income countries that so desperately needed this grain."

Following a series of coordinated strikes across Ukraine this Monday morning, Ukraine's largest private energy company DTEK says it's running out of equipment and spare parts needed for repairs of the damaged infrastructure facilities.

“Unfortunately, we have already used up the stock of equipment that we had in our warehouses after the first two waves of attacks that have been taking place since Oct. 10,” said DTEK Executive Director Dmytro Sakharuk. “We were able to purchase some equipment. But unfortunately, the cost of the equipment is now measured in hundreds of millions of dollars.”

Most parts have been already used for repairs following previous Russian strikes, he added.

Russia on Monday morning again launched a series of coordinated strikes across Ukraine, targeting energy infrastructure, including in the Kyiv region.

Ukraine's military said it shot down 44 cruise missiles as the Russians launched "several waves of missile attacks on critical infrastructure facilities" across the country.

About five distant booms could be heard in central Kyiv at about 8 a.m. local time.

Kyiv's mayor, Vitali Klitschko, confirmed that a power plant has been hit, meaning mid-morning around 350,000 homes in the capital were left without power. Kyiv's water supply has also been compromised, according to a water company.

A local official said "critical infrastructure" had also been hit in the Chernivtsi region in southwestern Ukraine.

Critical infrastructure has also been hit and damaged in Zaporizhzhia in the south, according to another local official.

Other regions of Ukraine appear to have been targeted, including Kharkiv, Odesa, Dnipro, Poltava and Lviv.

There are currently no reports of significant casualties.
