German Chancellor Friedrich Merz, on an unannounced visit to Kyiv, addressed Vladimir Putin on Sunday outside the National Academy of Sciences of Ukraine, which a Russian drone hit on September 28. "Mr. Putin, stop this senseless war! We are ready for talks, we are ready to speak with each other about ending this war. But these barbaric attacks on the civilian population of Ukraine must stop," he said, while sirens sounded in the city. "We can talk, but only once the weapons fall silent," Merz added.
