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

Speaking at a joint press conference with France's Emmanuel Macron, President Joe Biden said he would be open to speaking with Vladimir Putin if the Russian leader has legitimate interest in peace negotiations. Biden, however, said he has "no immediate plans to contact Mr. Putin."

Biden also noted that Putin has "miscalculated every single thing" when it comes to this war.

"So the question is what is his -- how does he get himself out of the circumstance he's in? I'm prepared if he's willing to talk to find out what he's willing to do, but I'll only do it in consultation with my NATO. I'm not going to do it on my own," Biden said.

Meanwhile, President Macron, who has continued speaking with Putin, said it's up to Ukraine to come to the negotiating table.

"So it's only legitimate that President Zelenskyy sets some conditions to talk. We need to work on what could lead to a peace agreement. But it's for him to tell us when the time comes and what the choices of the Ukrainians are," Macron said.

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.
