The United Nations says Russia's unprovoked invasion of Ukraine is a violation of the UN Charter and that the conflict, which is now in its 100th day, "has taken an unacceptable toll" on people.
"This war has and will have no winner. Rather, we have witnessed for 100 days what is lost: lives, homes, jobs and prospects," Amin Awad, the UN's assistant secretary-general and crisis coordinator for Ukraine, said in a statement on June 3.
"This war has taken an unacceptable toll on people and engulfed virtually all aspects of civilian life," Awad added.
Ukrainian President Volodymyr Zelenskiy said on June 2 that Moscow was now in control of 20 percent of Ukrainian territory, including Crimea, illegally annexed by Russia in 2014, and parts of eastern Ukraine that were seized by Russia-backed separatists the same year.
"In just over three months, nearly 14 million Ukrainians have been forced to flee their homes, the majority women and children," the statement said.
The UN said the organization was working to limit the war's "devastating impact on food security by seeking to unblock critical grain and commodity trade."
Food prices have surged because of a drop in grain exports from Ukraine -- one of the world's top producers.
"Our tireless efforts to respond to the war’s devastating impact will continue, robustly and stead-fast," the statement said.
"But above all we need peace. The war must end now."
