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

Electricity was back for 60% of customers in the Ukrainian city of Kherson, but shelling overnight damaged power lines, according to the head of Ukraine's regional energy company.

Workers are hoping to finish the repairs by the end of Thursday.

In Kyiv, 652,000 residents were subject to power outages throughout Thursday, according to the director of YASNO energy company, Serhiy Kovalenko. Kyiv's main power grid is operating at less than 70% capacity and 20% of residents are still without power or heat.

Russian Foreign Minister Sergey Lavrov accused the West of being directly involved in the war in Ukraine by supplying the country with weapons and training its soldiers.

"You are training their military on your territory, on the territories of Britain, Germany, Italy and other countries," Lavrov said at a press conference Thursday.

Lavrov also claimed that Russian missile strikes on Ukrainian energy facilities and other key infrastructure were intended to weaken Ukraine’s military potential and derail the shipments of weapons from the West.

Lavrov also said Moscow is open to peace talks to end the conflict.

The U.S. will provide Ukraine with more than $53 million to acquire critical electric grid equipment to help its citizens get through the winter, the State Department announced Tuesday.

The announcement comes amid Russia's continued attacks against Ukraine's energy infrastructure.

"This new assistance is in addition to $55 million in emergency energy sector support for generators and other equipment to help restore emergency power and heat to local municipalities impacted by Russia’s attacks on Ukraine’s power system," the State Department said in a release.

Denise Brown, the United Nations Resident Coordinator in Ukraine, traveled to the Ukrainian cities of Kherson and Mykolaiv over the weekend to get an update on the humanitarian issues affecting the southern part of the country, according to the U.N.

Although repairs to the area's water system are finally able to commence, there is still a lot of work to be done to help the people in those cities, the U.N said.

"We continue to be concerned about the plight of civilians in Ukraine especially as winter sets in," a U.N. spokesperson said in a statement.

Some heating points have already been established in Mykolaiv to help people who cannot heat their homes, according to the U.N.

"Aid workers are providing supplies and generators to make these places functional," the U.N. said in a statement.

The agency added that donations and funding for humanitarian efforts are critical as the cold weather sets in.
