Russia-Ukraine updates: Putin suspends key US-Russia nuclear treaty

National Security Council spokesperson John Kirby provided a preview Friday of President Joe Biden's upcoming trip to Poland, saying the president's main message will be continued support from the United States in the face of Russian aggression.

"On Tuesday evening, local time, President Biden will deliver remarks in Warsaw on how the United States has rallied the world to support the people of Ukraine as they defend their freedom and democracy. President Biden will make it clear that the United States will continue to stand with Ukraine, as you've heard him say many times, for as long as it takes," Kirby said of Biden's major planned address.

"As we approach the one-year mark since this invasion, we can proudly say that our support for Ukraine remains unwavering and our alliances and our international coalition in support of Ukraine remain stronger than ever," he added.

Biden is scheduled to arrive in Poland on Tuesday morning and meet with Polish President Andrzej Duda. On Wednesday, he'll meet with leaders from the so-called Bucharest Nine --Bulgaria, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania and Slovakia -- which are nine NATO countries in Eastern Europe.

Kirby was asked about Biden meeting Ukrainian President Volodymyr Zelenskyy, or traveling anywhere besides Warsaw, like the border town of Rzeszow, but he shot down both ideas.

"There is no meeting with President Zelenskyy scheduled for the trip right now," he said. "Right now, the trip is going to be in Warsaw."

Vice President Kamala Harris met with the leaders of France and Germany Friday as part of a U.S. diplomatic push in Munich to show strong, continued support for Ukraine.

Questions lingering over the leaders in Munich include how long the West can maintain its support for Ukraine –- amid declining public and political support at home –- and how Ukraine will withstand the expected Russian offensive.

A White House official said that at the meetings, the vice president planned to “recognize the courage and resilience shown by the people of Ukraine; reaffirm the support of American people for Ukraine; commend the international community on the historic actions taken since February 2022; celebrate Transatlantic unity and clarity of purpose; reaffirm our security commitments to our European allies; and condemn Russia’s continued illegal and brutal actions while calling for accountability and justice.”

She also planned to discuss “relations with China and actions to address the climate crisis,” the official said.

Belarus is ready to make Russian attack planes, Belarusian President Alexander Lukashenko said at a meeting with Russian President Vladimir Putin on Friday.

"Belarus has been making up to a thousand components for MC-21 and Superjet 100 planes. There used to be repair plants, but now they also make component parts," Lukashenko said.

"We are even ready to make it in Belarus with a little support from Russia," Lukashenko said.

Vice Prime Minister Iryna Vereshchuk called on the roughly 6,000 civilians still in Bakhmut to evacuate "immediately."

Officials said they don't want the people still in the city to put themselves and their children at risk and don't want them to interfere with the Ukrainian army. Five civilians were killed and nine others were injured on Thursday, according to the vice prime minister.

"Frankly speaking, I am very surprised that 6,000 civilians are still working there," Vereshchuk said in a statement.
