Russia said on Tuesday the suspension of U.S. aid to Ukraine following a public clash between their leaders, Donald Trump and Volodymyr Zelensky, was the best contribution to ending the Russia-Ukraine war.

"If the United States stops (military supplies), this would probably be the best contribution to peace," Kremlin spokesman Dmitry Peskov said, adding that it was a "solution which could really push the Kyiv regime to a peace process".
