Russia pounded Kyiv with missiles and drones on Thursday in its biggest attack on the Ukrainian capital this year, killing at least 12 people and drawing a rare rebuke from U.S. President Donald Trump who told the Russian president, ¡°Vladimir, STOP!¡±

Trump told reporters at the White House that his administration was applying ¡°a lot of pressure¡± on Russia and reiterated his displeasure with the attack.

But he said significant progress had been made in peace negotiations and the Kremlin had made a ¡°pretty big concession¡± by being open to ¡°stopping the war, stopping taking the whole country,¡± referring to Ukraine.
