Kyiv’s European allies slapped new sanctions Tuesday on Moscow, a day after a phone call between U.S. President Donald Trump and Russian President Vladimir Putin failed to produce a breakthrough.

Putin repeated his stance that “root causes” of the conflict must be addressed before any ceasefire is agreed, reported Russian state news agency TASS. These causes have included the Kremlin’s calls to restrict Ukraine’s sovereignty and prevent Kyiv from having closer ties in Europe.

Vladimir Putin is “trying to buy time” to continue his war in Ukraine, Volodymyr Zelensky has warned, after Donald Trump insisted progress had been made after his two-hour call with the Russian president.

Russia said on Tuesday that Ukraine had to decide whether or not it would cooperate in discussing a memorandum ahead of a potential future peace accord that Moscow has discussed with the United States.

U.S. President Donald Trump’s phone calls with the leaders of Russia and Ukraine have deepened expectations that progress might soon be made on ending those countries’ more than three-year war

Greece's Foreign Minister in an interview with the Associated Press addressed global issues, including the conflicts in Gaza and Ukraine.

Russia has battered Ukraine overnight with its largest drone attack since the war began, Ukraine’s military said Sunday, as Moscow intensified its military assault despite holding direct peace talks with Kyiv Friday.

Ukrainian officials and analysts say Ukrainian President Volodymyr Zelenskyy has few options but to draw U.S. President Donald Trump’s ire against Vladimir Putin, while depending on Europe’s support.
