Ukrainian officials said a Russian drone struck a nuclear fuel storage facility near Chernobyl on Sunday, partially destroying the site and sparking a fire that was extinguished within an hour.
Three people were killed in a separate Russian drone strike while waiting at a bus stop in Balabyne in the Zaporizhzhia region, and one person was wounded, the head of the regional military administration, Ivan Fedorov, wrote on his Telegram channel.
The damaged storage center is located in the Kyiv region, about nine miles from the Chernobyl nuclear power plant, and Energoatom wrote on Telegram that the attack "partially destroyed" the facility, which it said was empty at the time; the operator said the fire spanned roughly 40 square meters, or 430 square feet.
Officials said radiation remains within safe levels following the attack.
International Atomic Energy Agency chief Rafael Grossi said the incident was "deeply concerning" because of the large amounts of nuclear material held at the facility and said the agency would visit the site soon.
Ukrainian President Volodymyr Zelensky said the facility was hit by a Shahed drone and called the strike "extremely vile."
British Prime Minister Keir Starmer hosted leaders of Ukraine, France and Germany for talks scheduled Sunday evening, including French President Emmanuel Macron and German Chancellor Friedrich Merz, with Ukrainian President Zelensky participating.
The meeting followed a major Ukrainian drone strike that targeted St. Petersburg on Saturday; St. Petersburg Gov. Alexander Beglov said three people sustained minor injuries in that attack.
With the front line barely moving, both sides have sought an edge by launching long-range strikes, and swarms of drones have hindered advances, the reports said.
A Ukrainian attack also killed one man and injured a woman in Russia's Kursk region, local Gov. Alexander Khinshtein said.
