Ukrainian President Volodymyr Zelenskyy reported on September 26th, 2025, that his team conducted over 30 events in the United States, including meetings with President Donald Trump and the First Lady, aimed at strengthening cooperation and building new ties. During this period, a downed Russian unmanned aerial vehicle (UAV) exploded approximately 800 meters from the South Ukraine nuclear power plant, highlighting ongoing nuclear security risks, according to the International Atomic Energy Agency (IAEA). IAEA Director General Rafael Grossi expressed concern over the incident near the nuclear facility, emphasizing the risks to nuclear security during military conflict. Concurrently, a fuel train collided with a truck on a railroad crossing near Smolensk, Russia, causing a derailment and a significant fire, which has suspended railway traffic on that section. The driver's actions were described as having resulted in a "local apocalypse." President Zelenskyy stated that these efforts in the U.S. serve "one purpose – our country’s strength," intended to protect people, end the war, and restore peace. He expressed gratitude for support from all countries and individuals assisting Ukraine. The International Crimea Platform Summit and the International Coalition for the Return of Ukrainian Children Summit were also mentioned as significant events held on a global stage. The incident near the South Ukraine nuclear power plant underscores the persistent dangers in the region. The collision in Smolensk occurred near the same time as previous reports of heightened regional instability. Earlier on September 26th, Poland had urged its citizens to leave Belarus due to rising tensions and arbitrary arrests, and a fuel train had collided with a truck in Russia's Smolensk region, causing a fire.
