Ukraine's President Volodymyr Zelensky announced that Ukrainian forces successfully tested a new defense system capable of intercepting Russian drones. During the test, a drone of Iranian design known as a "shahed" was destroyed. Zelensky reported that Ukrainian military forces had intercepted 187 airborne targets overnight, with 93% of all Russian drones shot down. While he acknowledged the success of the operation, he emphasized that further improvements are needed to refine the technology. The test comes amid ongoing Russian drone attacks across Ukraine, which have targeted both military and civilian infrastructure. Ukraine's air force issued multiple warnings since midnight about incoming threats from Russian drones, guided aerial bombs, and missiles. In Kyiv, a Russian strike caused a fire at a warehouse in the early hours of the morning. Meanwhile, Denmark accused Russia of firing flares dangerously close to a military helicopter without warning or communication. In response, Russia criticized Danish military helicopters for making "dangerous" maneuvers near its warships in the Baltic Sea. Russia’s ambassador to Denmark, Vladimir Barbin, reportedly delivered an official note to Copenhagen, as reported by the Russian news agency RIA. In the United States, the FBI announced that it had thwarted a Russian plot to carry out targeted killings and acts of terrorism in the U.S. and European countries supporting Ukraine. Federal authorities charged five individuals linked to Russian intelligence with planning to surveil and kill targets in the U.S. and Europe. The FBI stated that its efforts to uncover and stop these plans have been "relentless." Russian ice hockey star Alexander Ovechkin was asked by the Russian government to appear in a political campaign ad for the United Russia party, which supports President Vladimir Putin. Ovechkin was in Russia during the offseason and received the request, according to his team, the Washington Capitals. The team clarified that Ovechkin's focus remains on the upcoming hockey season and that the campaign appearance was not a reflection of his personal views. Russia's foreign ministry accused Western politicians of ignoring warnings not to visit Ukraine. It urged foreign diplomats to "soberly" assess the risks of visiting the country, as Russia had previously advised diplomats to leave Kyiv due to its military strikes. During a visit by former UK Prime Minister Boris Johnson to Kyiv, a Russian drone targeted a stationary passenger train near his train as he returned from a security conference. Meanwhile, Poland has increased security at its border with Ukraine after Russian drone attacks near NATO guard posts. A drone hit a passenger train on the border, and another struck a truck at a nearby petrol station. As a result, border guards suspended crossings and evacuated vehicles for safety. The UN humanitarian coordinator in Ukraine, Matthias Schmale, said the organization is considering moving aid supplies underground to protect them from Russian attacks. Russia has struck 10 of the UN’s warehouses this year, destroying millions of pounds worth of supplies. Schmale noted that attacks on aid storage facilities have become a new trend, prompting the UN to delay purchasing supplies until the last possible moment to reduce the risk of damage from strikes.
